For some time, I have been curious about how often researchers are downloading and using my R packages. However, there has been no way to satiate this curiosity...until now! Thanks to Tal Galili (at http://www.rstatistics.com/), interested parties can answer the question: “How many people use a particular R package?” Using Tal's R scripts, I generated several bar charts for the daily number of downloads for each of my packages from 04022013 (approx. date R 3.0.0 was released) until 06162013. So, about 2.5 months in sum. Above and below are the graphics for the top 2 package. Below displays the total number of downloads for each package during this 2month period. The package 'compute.es' took the lead with over 500 downloads in just over 2months. All of these packages combined totaled about 2,000 downloads during this short period. Below is the R output for each of my R packages. These are the total downloads from around the date R 3.0.0 was released (04022013) until 06162013. So, about 2.5 months in sum. > barplot_package_users_per_day("compute.es", my_RStudio_CRAN_data) $total_installations [1] 531 > barplot_package_users_per_day("RcmdrPlugin.MA", my_RStudio_CRAN_data) $total_installations [1] 446 > barplot_package_users_per_day("MAd", my_RStudio_CRAN_data) $total_installations [1] 515 > barplot_package_users_per_day("MAc", my_RStudio_CRAN_data) $total_installations [1] 396 Looks like 'compute.es' package has the most downloads during this 2 1/2 month period at 531 total installations! Pretty rad!
