Major update to the contributers list in the DESCRIPTION file!
Fix question in require2
BUG FIX: install.URL didn't work on Windows. It was because "system" did not run .exe, and "shell" was the correct choice to use here. It is now fixed.
minor
added reference to R.utils::installPackages(url)
Added NEWS.md
Update install.r

Noticed that the docs said things like `install.MikTeX() # installs the latest version of git`
Merge pull request #6 from tjmahr/patch-1

Update install.r - fix docs
Added a packages= option to read_RStudio_CRAN_data

read_RStudio_CRAN_data fails on out-of-memory (in the rbindlist call) if you've downloaded many RStudio CRAN logs.  This patch adds a packages= option if you're only interested in a subset of packages, which subsets the daily log data on the fly.  Other such filters might also be added.
Merge pull request #7 from friendly/patch-1

Added a packages= option to read_RStudio_CRAN_data
install.pandoc - added "to_restart" parameter. With a massage to remind the user they should restart their computer after pandoc is installed.
Bump to 0.13.0

make checkMD5 issue warnings (maybe with a dialog box) instead of errors (since the current state of affairs is more hassle than it is worth...)
Updated some functions and documents in order to pass CRAN checks: RStudio_CRAN_data_folder, pkgDNLs_worldmapcolor, fetch_tag_from_Rd, add_to_.First_in_Rprofile.site, remove_from_.First_in_Rprofile.site, add_load_installr_on_startup_menu,README.md
Better use of "data" inside a function in a package.
Merge branch 'master' of https://talgalili:kukBsbmiFPf5FOqWKiuP@github.com/talgalili/installr/
Updated NEWS and manual for adding a packages= option to read_RStudio_CRAN_data.

read_RStudio_CRAN_data fails on out-of-memory (in the rbindlist call) if you've downloaded many RStudio CRAN logs.  This patch adds a packages= option if you're only interested in a subset of packages, which subsets the daily log data on the fly.  Other such filters might also be added.
