R i pakiet shiny. Kurs video. Interaktywne aplikacje w analizie danych
Alicja Wolny-Dominiak
Obierz kurs na... analizę danych W dzisiejszej praktyce biznesowej duże znaczenie mają dane i ich analiza. W analizie zastosowanie znajduje wiele modeli statystycznych, implementowanych w różnych programach komputerowych. Na przykład Excel ma specjalny dodatek, nazwany po prostu Analiza Danych. Bardzo popularne narzędzie stanowi program R, którego zaletą jest łatwe tworzenie dashboardów obliczeniowych automatyzujących operacje na danych i rysowanie wykresów z użyciem pakietu shiny. Pakiet ten jest oprogramowaniem typu open source, przeznaczonym także dla osób, które nie znają języków HTML, CSS i JavaScript. Ba, by tworzyć eleganckie i wydajne aplikacje internetowe w języku R, nie trzeba nawet być programistą. Pakiet shiny pozwala na automatyzację obliczeń, wizualizację danych i szacowanie modeli statystycznych stworzonych w R. Wbudowane w niego funkcje ułatwiają pracę z danymi – ich eksplorowanie i prezentowanie. Oprogramowanie to służy również do tworzenia dynamicznych dashboardów i paneli sterowania, które łączą różne wykresy, tabele, filtry i opcje wyboru, aby przedstawiać dane w czytelny i interaktywny sposób. Za jego pośrednictwem można przygotowywać także raporty – do tego celu służą odpowiednie aplikacje. Proponowany przez nas kurs wyjaśnia zasady działania pakietu shiny i uczy, jak z niego korzystać. Nabyte umiejętności mogą być dalej bezpośrednio przydatne podczas pracy z danymi i w trakcie analizy procesów biznesowych. Co Cię czeka podczas naszego profesjonalnego szkolenia W ramach kursu: Dowiesz się, jak zacząć pracę z pakietem shiny w RStudio Poznasz budowę prostej aplikacji rysującej histogram z szablonu w RStudio Przyjrzysz się budowie podstawowego interfejsu użytkownika ui – domyślne ui w pakiecie shiny Zobaczysz, jak wygląda rozszerzony interfejs użytkownika z wykorzystaniem innych pakietów przeznaczonych do korzystania z shiny Opanujesz zasady tworzenia serwera obliczeniowego i renderowania obliczeń w interfejsie użytkownika ui Dowiesz się, jakie jest zastosowanie reaktywnych możliwości w pakiecie Zrobisz update interfejsu użytkownika w trakcie pracy Zapoznasz się z wybranymi pakietami, które można zastosować w aplikacji webowej do renderowania danych i wykresów Stworzysz mapę w aplikacji webowej R i pakiet shiny. Kurs video. Interaktywne aplikacje w analizie danych kończy się na poziomie średnio zaawansowanym. Szkolenie pozwoli użytkownikowi zrozumieć sposób tworzenia aplikacji webowej w pakiecie shiny. Dalszy rozwój umiejętności jest uzależniony od wiedzy z zakresu programowania w języku R i w innych językach, głównie w JavaScripcie. Do czego i komu przydaje się język R Tematyka kursu ma zastosowanie przede wszystkim w wypadku osób pracujących na stanowiskach, na których używa się różnorodnych danych. W trakcie ich obróbki często powtarzają się te same schematy obliczeniowe – niezależnie od tego, jak zmienne są dane, na których się pracuje. By ułatwić sobie zadanie, zamiast w kółko powtarzać te same obliczenia, można zbudować w shiny aplikację webową, która będzie miała zakodowane schematy obliczeniowe w serwerze – jedyną zmienną będą wówczas dane wejściowe. Automatyzacja obliczeń bywa skomplikowana, ale jakże upraszcza życie!

If your company is like most, the number one reason that projects have failed over the years don’t have to do with technology. They have to do with people. People didn’t like the new technology. People weren’t trained properly on the change. People hadn’t received adequate communications and didn’t understand the change. Sound familiar?

Kiedy śmiertelnie niebezpieczna sekretna gra zagraża rzeczywistości, świat może uratować tylko jeden człowiek Rabbits to gra tocząca się w alternatywnej rzeczywistości, tak rozległa, że korzysta z całego świata jako planszy. Od momentu jej rozpoczęcia odbyło się już dziesięć edycji, w których ogłoszono dziewięciu zwycięzców. Ich tożsamość jest jednak nieznana. Podobnie jak nagroda, którą mogły być rzekomo rekrutacja do NSA lub CIA, bogactwo, nieśmiertelność, a może nawet klucz do tajemnic wszechświata. Jednak im głębiej wnika się w grę, tym niebezpieczniejsza się staje. Gracze ginęli już w przeszłości, a liczba ofiar rośnie. Właśnie zbliża się rozpoczęcie jedenastej edycji. K, pasjonat Rabbits, od lat próbuje dostać się do gry. Miliarder Alan Scarpio, podający się za zwycięzcę szóstej edycji, twierdzi, że z grą dzieje się coś niedobrego i że K musi ją naprawić, zanim zacznie się rozgrywka w przeciwnym razie świat się rozpadnie. Wkrótce po zaginięciu Scarpia rozpoczyna się jedenasta edycja. A losy całego wszechświata spoczywają w rękach jednego bohatera Spora doza tajemniczości w czasach konspiracyjnego szaleństwa, przerażająca historia, która przekonująco przypomina nam o niebezpiecznej wiarygodności teorii spiskowych. Cory Doctorow, autor Małego brata Rabbits to powieść zręcznie napisana i pełna intryg. Łączy w sobie surrealizm Haruki Murakamiego z porywającym tempem i popkulturowymi wrzutkami z filmu Player One. Zapiera dech! Nicholas Eames, autor Królów Wyldu

Historia Michaela jest historią młodego człowieka, jego dorastania w wielopokoleniowej żydowskiej rodzinie, pierwszych zauroczeń, wyborów życiowych i ich konsekwencji, czy w końcu miłości, która nie powinna się wydarzyć, bo przecież rabin nie ma prawa zakochać się w chrześcijance. Ta kronika życia zagubionego chłopaka, potem młodego rabina i w końcu dojrzałego mężczyzny została mistrzowsko przeczytana przez Janusza Zadurę. Autor Medicusa barwnie opisuje życie Żydów w Ameryce XX wieku z ich świętami, obrzędami, tradycjami czy modlitwami. Audiobook to nie tylko historia jednego człowieka, ale też pokazanie ortodoksyjnego życia w nieortodoksyjnym świecie.
