gather_cran: Gather CRAN details

In ropensci/rostats: rOpenSci stats reporting tools

Description

Gather CRAN details

Usage

gather_cran(pkg)

gather_crans(pkg)

cran_first_date(x)

Arguments

pkg	(character) a package name
x	a data.frame

Details

While gather_commits and gather_downloads cache data because data can take a long time to download, this function shouldn't take that long, even with hundreds of of pkgs.

## Not run: 
library("rostats")

url <- "https://raw.githubusercontent.com/ropensci/roregistry/gh-pages/registry.json"
df <- jsonlite::fromJSON(url)
(pkgs <- tbl_df(df$packages) %>%
  filter(on_cran | on_bioc) %>%
  .$name)
sort(pkgs)

# get first date on CRAN for each pkg
res <- gather_crans(pkgs)
alldat <- dplyr::bind_rows(res)

# get new packages on CRAN, arranged by date
alldat %>% cran_first_date() %>% arrange(desc(date)) %>% top_n(10) %>%
  readr::write_csv("../biweekly/data/newpkgs.csv")

# get new packages & new versions on CRAN, arranged by date
