ozcran

The goal of ozcran is to check the status and packages available from Australian CRAN mirrors.

Installation

You can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("mdsumner/ozcran")

Example

This is a basic example which gets the package list from Australian CRAN mirrors and provides a quick summary.

library(ozcran)

library(dplyr)
db <- oz_db() 
dim(db)
#> [1] 87487    65

db now is a data frame with lots of fields about every package, and reflects the status of at least five online mirrors. The mirror itself is named in the repos column.

Group by repository and find a summary of currency and number of packages.

db %>% group_by(repos) %>% 
  summarize(n = n(), date = max(as.Date(Published), na.rm = TRUE)) %>% 
  arrange(desc(date))
#> # A tibble: 6 x 3
#>   repos       n date      
#>   <chr>   <int> <date>    
#> 1 aws     14594 2019-07-22
#> 2 private 14594 2019-07-22
#> 3 curtin  14594 2019-07-21
#> 4 aarnet  14569 2019-07-15
#> 5 csiro   14569 2019-07-15
#> 6 unimelb 14567 2019-07-15

We can also compare to the source CRAN mirror that is in Austria (no kangaroos).

oz_db(include_cran = TRUE) %>% group_by(repos) %>% 
  summarize(n = n(), date = max(as.Date(Published), na.rm = TRUE)) %>% 
  arrange(desc(date))
#> # A tibble: 7 x 3
#>   repos       n date      
#>   <chr>   <int> <date>    
#> 1 aws     14594 2019-07-22
#> 2 cran    14594 2019-07-22
#> 3 private 14594 2019-07-22
#> 4 curtin  14594 2019-07-21
#> 5 aarnet  14569 2019-07-15
#> 6 csiro   14569 2019-07-15
#> 7 unimelb 14567 2019-07-15
