Hey there,
I tried to count the number of rows, where my data isn't NaN in a
certain column.
this was my guess:
(given is a data frame with 2069 rows and 17 cols)
NROW(data[jan,16] != NaN)
("jan" is defined this way: jan<- which(data[,2]==1, arr.ind= TRUE))
but I only get the number of columns where my data is "1" in the second
col. R isn't removing the NaN.
na.rm isn't working here.
I would appreciate your help.
