Oftentimes I see users attach a series of packages in the beginning of their scripts by repeating library() multiple times. R-xfun linux packages: rpm, tgz Then update the package, and it should succeed because it is not loaded nor any of its dependencies (except the core packages). Installed as above and I was able to install RMarkdown and create files. With the above example, xfun::magic_path('cars.csv') in a code chunk of docs/foo.Rmd will return ../data/cars.csv, if cars.csv is a unique filename in the project. invalid multibyte string likely refers to characters not recognized by the character encoding format..

Therefore I did a quick and dirty implementation in R, including functions gsub_files(), gsub_dir(), and gsub_ext(), to search and replace strings in multiple files under a directory. Currently it only supports R package projects and RStudio projects by default. The function from_root() was inspired by here::here(), but returns a relative path (relative to the project’s root directory found by proj_root()) instead of an absolute path. For example, you may only provide a base filename, and magic_path() will look for this file under subdirectories and return the actual path if it is found. fct_reorder() is useful for 1d displays where the factor is mapped to position; fct_reorder2() for 2d displays where the factor is mapped to a non-position aesthetic.

Other functions are also available to plot adjusted curves for ‘Cox' model and to visually examine ’Cox' model assumptions. The function numbers_to_words() (or n2w() for short) converts numbers to English words. To invalidate the cache when y has changed, you may let cache_rds() know through the hash argument that y needs to be considered when deciding if the cache should be invalidated: If you do not want to provide this list of value(s) to the hash argument, you may try hash = "auto" instead, which asks cache_rds() to try to figure out all global variables automatically and use a list of their values as the value for the hash argument.

A strict list is a list for which the partial matching of the $ operator is disabled. 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. C R Package Dependencies. README.md An Introduction to xfun Functions. Cancel.

Then start a R session with an empty environment, or a really new/empty RStudio project. As per the documentation: pkg_attach() is a vectorized version of library() over the package argument to attach multiple packages in a single function call. In such case, gh_update_package_list() is useful. You can choose to print out the versions of only the packages you specify, e.g., # this is more likely to be what you want to see, # pretend the computing here is a time-consuming, # feel free to make any changes in white spaces, Find files (in a project) without the pain of thinking about absolute/relative paths, Input a character vector into the RStudio source editor. If file paths are too much pain for you to think about, you can just pass an incomplete path to the function magic_path(), and it will try to find the actual path recursively under subdirectories of a root directory.
