I am struggling generating plots to compare coefficients from lme and lmList objects. I get this error message. plot(compareFits(coef(bp.lisA),coef(bp.lmeA))) Error in compareFits(coef(bp.lisA), coef(bp.lmeA)) : Objects must have coefficients with same row names In addition: Warning message: longer object length is not a multiple of shorter object length in: sort(dn1[[1]]) != sort(dn2[[1]]) There are some groups with one observation which are dropped from the lmList object. I have tried matching on the row.names but running into trouble. Is there any other method that may work Thanks Ross Darnell -- -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
