In R: How can I know if my packages are up to date?

Question

I am looking for a function that will tell me, for a list of packages, which of them is up to date and which is not (I need it so to trace back an R crash).

Thanks,

Tal

Answer 1

Well, you could just update them with the update.packages() function.

You could use installed.packages() and available.packages() to find any differences. Just merge the two results together on the name, and then look for version differences.

i <- installed.packages()
a <- available.packages()
ia <- merge(i, a, by="Package")[,c("Package", "Version.x", "Version.y")]
ia[as.character(ia$Version.x) != as.character(ia$Version.y),]

And that 'comparison by sets' is basically what CRANberries does to compute new or changes packages. – Welldefined

old.packages will list the out of date ones. – Acoustician

updateme is a really handy package that indicates if a new package version is available:

# install.packages("updateme")
library(updateme)
library(tidyverse) # check if there any new versions of tidyverse packages available
