Dear all,

Sorry, I means if we must remove the nonparameter value then do the

Hi,

when I run the below code,there is an error occured. could you please tell

+  panel=function(x,y) { points(x,y); lines(lowess(x,y))})
Error in `[.data.frame`(data2, , c(ID, TYPE, AGE, GNDR, HT)) :

 when I try colnames(data2) or names(data2) ,it shows as follows:
