I was trying to compile a function in R and came across this error
loadchar() <- function( path, filename){ …
}
Error in loadchar() <- function(path, filename) { :
invalid (NULL) left side of assignment
I couldn’t find much on the internet but the answer (in my case at least) was simple…
The issue is the brackets in the function name ie it should be
loadchar <- function( path, filename){ …
}
an easy mistake to make … especially if you are jumping between languages regularly
