Hi All. I am a new R user. Trying to do scatterplot. Not sure how to resolve this error message A<-subset (ErablesGatineau, station=="A")
B<-subset (ErablesGatineau, station=="B") plot(diam ~ biom)
Did you also attache either (or both??? of those data.frames)?
abline(lm(diam ~ biom), col = "red") goodcases <- !(is.na(diam) | is.na(biom)) lines(lowess(diam[goodcases] ~ biom[goodcases])) library(car) scatterplot(diam ~ biom, reg.line = lm, smooth = TRUE,
+ labels = FALSE, boxplots = FALSE, span = 0.5, data = A) Error in `row.names<-.data.frame`(`*tmp*`, value = FALSE) : invalid 'row.names' length
Given the fact that you deemed it necessary to "pre-qualify" your data when you constructed "goodcases", the invalid row.names length error suggest you may need to supply scatterplot() when using the reg.line argument with data that has been similarly culled of NA values. ?complete. case ?na.omit Perhaps trying with a data=A[goodcases, ]
