Good evening!
I don't know R, but I have to do this work for my diploma. So I'm sorry for
the strange message below. Help me anybody decides this issues, please.
a part of the code is:
for (i in 1:133) {
r_squared <- vector()
sample_bank <- mydata[((i-1)*311+1):(i*311),]
#return for bank
return_bank <- diff(sample_bank[,4])/sample_bank[,4][-length(sample_bank[,4])]
I've got these errors:
model <- lm(sample_est[,6] ~ sample_est[,7], na.action=na.omit)
Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) : 0
(non-NA) cases
In addition: Warning message :
In Ops.factor(diff(sample_bank[, 4]), sample_bank[, 4][-length(sample_bank[, :
‘/’ not meaningful for factors ( how to change type of columns that it works
well?)
colnames(ab_ret) <- as.character(col_nam)
Error in `colnames<-`(`*tmp*`, value = character(0)) : attempt to set colnames
on an object with less than two dimensions If there are not enough information..

I tried to find answers on stackoverflow, but it didn't help me.
I'm sorry, I can't explain well because don't know R and English well.
I'll be glad any helpful information.
Thank you.
