Example use of datastorr.

devtools::install_github("richfitz/datastorr")
devtools::install_github("richfitz/datastorr.example")

Usage

To start with there is no data present:

datastorr.example::mydata_versions()

## character(0)

Though there are versions on github:

datastorr.example::mydata_versions(local=FALSE)

## [1] "1.0.0" "1.0.1" "1.0.2"

Retrieve the data:

system.time(d <- mydata())

##    user  system elapsed
##   0.036   0.005   1.152

The progress bar looks a bit messed up but should work well interactively. The relevant time is the elapsed time, rather than user or system time.

The data in all its glory:

head(d)

Subsequent calls are very fast:

system.time(d <- mydata())

##    user  system elapsed
##   0.001   0.000   0.002

The local versions:

datastorr.example::mydata_versions()

## [1] "1.0.2"
