repmis

Version 0.4.4

Miscellaneous tools for reproducible research

Functions

repmis currently has the following functions:

Functions for installing, loading, and citing R packages:

• LoadandCite: a function for installing and loading R packages. The command also creates a BibTeX bibliography file with package citations.

• InstallOldPackages: installs specific R package versions.

Functions for loading data into R from the internet:

• source_data: loads plain-text formatted data (e.g. CSV, TSV) or RDATA stored at a URL (both http and https) into R. Note: the command can download data from almost any secure (https) URL. This includes data in Dropbox Public folders and published Google Docs plain-text formatted data sets (see Google Docs support pages for details. Note, currently only the old Google Sheets supports publishing sheets to the Web as plain-text files.)

  • source_data, and all of the data download commands in repmis find and report SHA-1 hashes for each file it loads. You can use a file's SHA-1 hash to make sure you are downloading the file and version of the file you think you are downloading. Note: if you are using source_data to download data from GitHub, source_data's SHA-1 hash is not the same as the Git commit's SHA-1 hash. (Thanks to Hadley Wickham's devtools package for the code to make this possible.)

  • Data downloaded with source_data can be cached (so you don't have to re-download it every time you run a script. To do this use the cache argument.

• source_DropboxData: loads plain-text formatted data stored in a Dropbox non-Public folder. See this blog post for more details. Also, if you are looking for full Dropbox control (not just data downloading) from R see Karthik Ram's rDrop package.

• source_XlsxData: downloads and loads a data set in Excel format. The function relies on the xlsx package and can take any arguments that read.xlsx can.

Other

• git_stamp: function for get git stamp (commit and branch) for a repository. Thanks to Måns Magnusson.

• scan_https: read a character text file from a secure (https) site into R as a single object.

• set_valid_wd: sets valid working directory from vector of possible directories. This is useful if you run the same script on multiple machines.
