Find out what encoding the file has (often issue when files were generated on for example Mac and then used on Windows or vice versa) and then specify that in R like so: Bioconductor version: Release (3.12) Using R enviroments for annotation. Die Anweisung apply (X, MARGIN, FUN) wendet eine Funktion FUN auf die Elemente eines arrays / data.frames an. This function also makes use of raw_string(), so you can see the content of a file in the console as a side-effect, e.g.. requested, Kill a process and (optionally) all its child processes, Evaluate an expression under a specified working directory, Some utility functions for checking packages, Get the tags of Github releases of a repository, Get the relative path of a path in a project relative to the current working After typing the code x = grep(pattern, x, value = TRUE); gsub(pattern, '\\1', x) many times, I combined them into a single function xfun::grep_sub(). This package contains several utility functions that I frequently use in other packages, and also miscellaneous functions that I use by myself from time to time. The tricky thing about knitr’s caching is how it decides when to invalidate the cache.For xfun::cache_rds(), it is much clearer: the first time you pass an R expression to this function, it evaluates the expression and saves the result to a .rds file; the next time you run cache_rds() again, it reads the .rds file and returns the result immediately without evaluating the expression again. By default, it returns a relative path, which is relative to the current working directory. The series of functions is_linux(), is_macos(), is_unix(), and is_windows() test the types of the OS, using the information from .Platform and Sys.info(), e.g.. Oftentimes I see users attach a series of packages in the beginning of their scripts by repeating library() multiple times.

Contains the function 'ggsurvplot()' for drawing easily beautiful and 'ready-to-publish' survival curves with the 'number at risk' table and 'censoring count plot'. If you are not using a project to manage files, magic_path() will look for the file under subdirectories of the current working directory. I want it, or I do not want. 'Roxygen2' is inspired by the 'Doxygen' system for C++. Then I did restart to install the xfun package again, then it suddenly showed the version 0.19 of xfun package.
