sm.density.compare
Hi James,
Error in if (from == to) rep.int(from, length.out) else as.vector(c(from, : missing value where TRUE/FALSE needed ... ... The only difference with my data is that I have some missing values that show as NA
This is precisely the problem. ## Show the error [message] y <- rnorm(100) y[c(3,6,9,12,20,56)] <- NA g <- rep(1:2, rep(50,2)) sm.density.compare(y, g, model="equal") ## One way around the problem is row-wise deletion of NAs na.omit(cbind.data.frame(y,g)) with(na.omit(cbind.data.frame(y,g)), sm.density.compare(y, g, model="equal")) Regards, Mark.

I am running the?sm.density.compare function amd I am getting the following error: ? my code is? > sm.density.compare(LBSTRESN,COHORT,xlab="Units = umol/L"subset = LBTEST=="Creatinine") ? Error in if (from == to) rep.int(from, length.out) else as.vector(c(from,? : ? missing value where TRUE/FALSE needed ? I do not understand the error and I have had no help when searching the WEB or the R documentation. ? I have tried the sample program in the R doc:y <- rnorm(100) g <- rep(1:2, rep(50,2)) sm.density.compare(y, g, model="equal") ?and it works fine. ?The only difference with my data is that I have some missing values that show as NA. I have checked that theseare numbered values by using the is.nan function.?Any ideas??Thank You?Jim L.? [[alternative HTML version deleted]]
