RegisterData frame challenge [🇷 for BE/BA]
I am a fan of the data.table package. So my answer would be this:
You need to do it in two steps, else the class stays character.
library(data.table)
a <- fread("./test.csv", colClasses = "character")
a <- a[, lapply(.SD, as.numeric)]
a <- a[, lapply(.SD, function(x){ifelse(is.na(x), 0, x)})]
You need to do it in two steps, else the class stays character.
