Run go install and

• gogitlocalstats -add /path/to/folder will scan that folder and its subdirectories for repositories to scan
• gogitlocalstats -email [email protected] will generate a CLI stats graph representing the last 6 months of activity for the passed email. You can configure the default in main.go, so you can run gogitlocalstats without parameters.

Being able to pass an email as param makes it possible to scan repos for collaborators activity as well.

Update: The timings are now updated with runs from R v3.1.0.

A small note on this tweet from @KevinUshey and this tweet from @ChengHLee:

The number of rows, while is important, is only one of the factors that influence the time taken to perform the join. From my benchmarking experience, the two features that I found to influence join speed, especially on hash table based approaches (ex: dplyr), much more are:

• The number of unique groups.
• The number of columns to perform the join based on - note that this is also related to the previous point as in most cases, more the columns, more the number of unique groups.

That is, these features influence join speed in spite of having the same number of rows.

#' Simplified loading and installing of packages
#'
#' This is a wrapper to \code{\link{require}} and \code{\link{install.packages}}.
#' Specifically, this will first try to load the package(s) and if not found
#' it will install then load the packages. Additionally, if the 
#' \code{update=TRUE} parameter is specified it will check the currently 
#' installed package version with what is available on CRAN (or mirror) and 
#' install the newer version.
#' 
#' @param pkgs a character vector with the names of the packages to load.
