Hi again, I tried to recode variables in my dataset using the follwing code
ckd[ckd$`seen filter`==1,]$`seen filter` <- "yes"
This is what I got
Error in `[<-.data.frame`(`*tmp*`, ckd$`seen filter` == 1, , value = list( :
missing values are not allowed in subscripted assignments of data frames
How can I remove NAs here inside this code
