R awesome!
- CVSkit is a suite of utilities for converting to and working with CSV, the king of tabular file formats. It is inspired by pdftk, gdal and the original csvcut utility by Joe Germuska and Aaron Bycoffe.
- dplyr and pipes: the basics. The dplyr R package is awesome. Pipes from the magrittr R package are awesome. Put the two together and you have one of the most exciting things to happen to R in a long time.

Автообновление R
Upgrading to R 3.1.1 on Windows
If you are using Windows you can easily upgrade to the latest version of R using the installr package. Simply run the following code:
# installing/loading the latest installr package: install.packages("installr"); require(installr) #load / install+load installr updateR() |
After running “updateR()”, the function will detect that R is available for you, and will download+install it (etc.).

•Use str() for displaying object values
Теперь переменные открываются не в текстовом редакторе, а в окне в усеченном виде. Показывает сводку по структуре (в отличии от ранее открывавшегося во внешнем файле текстового представления всей переменной) - Функции для отображения данных: str(), summary(), ls.str(), ls()

- Если данных не хватает в исходном источнике, то ts начинает гнать по кругу и добивает недостающие не NA, а данными с начала источника

How to change language setting of R on Windows
I read FAQ on CRAN, but it was a bit confusing to a novice like me. So here is the screenshot. First, go to the "etc" folder under R program files folder. Then locate Rconsole file. Find the line "language = ", change it to "language = en" if you want to run R in English. Save the file. Windows (I am using Windows 7.) told me that I have no permission to change the Rconsole file and that I should contact the administrator. Thank you. ! I am the administrator/user. I had to right click on the Rconsole file icon, select Property and grant a permission to modify the file to myself, the user. - Установка паузы при выводе графиков ("Hit
to see next plot ")
par(ask = TRUE). Если правильно понимаю, то это все работает для девайса вплоть до перезагрузки (в RStudio). - Смена языка вывода сообщений в коде:
You can set this using the
Sys.setenv() function. My R session defaults to English, so I'll set it to French and then back again:> Sys.setenv(LANG = "fr")
> 2 + x
Erreur : objet 'x' introuvable
> Sys.setenv(LANG = "en")
> 2 + x
Error: object 'x' not found
- Красивая тема для ggplot2:
Thanks! Yup, it's a custom theme (a work in progress). You can find it here: https://github.com/noamross/no...
Glad it's useful. Note you can get "Lato Light" from Google Web Fonts, and you may want the R package "extrafont" to get the font into PDF figures.
