I have a list of named values:
myList <- list('A' = 1, 'B' = 2, 'C' = 3)
I want a vector with the value 1:3
I can't figure out how to extract the values without defining a function. Is there a simpler way that I'm unaware of?
library(plyr)
myvector <- laply(myList, function(x) x)
Is there something akin to myList$Values to strip the names and return it as a vector?

Use unlist with use.names = FALSE argument.
unlist(myList, use.names=FALSE)
purrr::flatten_*() is also a good option. the flatten_* functions add thin sanity checks and ensure type safety.
myList <- list('A'=1, 'B'=2, 'C'=3)
purrr::flatten_dbl(myList)
## [1] 1 2 3
This can be done by using unlist before as.vector.
The result is the same as using the parameter use.names=FALSE.
as.vector(unlist(myList))
