I want to do a lm regression, some of the variables are going to be affected with log, I would like not no take into account the values which imply doing log(0)
for just one variable I have done the following but it doesn't work: lmod1.lm <- lm(log(dat$inaltu)~log(dat$indiam),subset=(!(dat$indiam %in% c(0,1))) and obtain: Error en lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) : 0 (non-NA) cases lmod1.lm <- lm(log(dat$inaltu)~log(dat$indiam),subset=(!(dat$indiam = 0)), na.action=na.exclude) and obtain Error en lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) : NA/NaN/Inf en llamada a una función externa (arg 1) Thanks, u...@host.com -- View this message in context: http://r.789695.n4.nabble.com/lm-log-variable-skip-log-0-tp3324263p3324263.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
