error in lm.fit
Hello R user,
I have several data frames with >100 columns and I did a linear regression
over time of each column
df1.lm <- lapply(df1, function(x) lm(x~year)$coeff[2])
that worked fine and I get slope of each column oder time - until I divided
df1 by df2
df3 <- df1/df2
> df3.lm <- lapply(df3, function(x) lm(x~year)$coeff[2])
Error in lm.fit(x, y, offset = offset, ...) :
