The Internet websites of MRAN and METACRAN can help the package deal assortment system by supplying more info on my sources Each individual bundle uploaded to CRAN. METACRAN, such as, gives metadata about R packages by using a straightforward API and the provision of ‘badges’ to show the quantity of downloads a specific offer has a month.
Could it be mature? The greater time a deal is on the market, the more time it will likely have for clear bugs to become ironed out.
