This is a macOS QuickLook Plugin for R data files.

That means if you install this plugin (download and unzip and put QuickLookR.qlgenerator into ~/Library/QuickLook) you can hit the spacebar on an R Data or saved RDS file (.rdata, .rda, .rds are currently supported extensions) and get a str() preview without firing up R/RStudio.

It looks for Rscript in /usr/local/bin and (for now) requires a helper package rdatainfo. devtools::install_github("hrbrmstr/rdatainfo") to install that.

For the moment, the QuickLook preview is rather plain, but I hope to improve the output and switch to reading the data files at the C-level by linking directly to R.framework.
