This is my function:
zywnoscCalosc <- function( zywnosc, sklepik, sklslodycze) {
b=as.vector(sklslodycze)
fun=function(a,b){
a=2+b
}
zywnosc=ifelse(is.na(sklepik),NA,fun(a,b)) #Here I have a problem !
}
I always get: Error in 2 + b : non-numeric argument to binary operator
I think problem is in my vector b. What I should do to get restult my
function fun(a,b) inside "zywnosc"?
