Hi all, I have some little questions. 1) I make a function, with list's help, for make a map, its work OK, but it show an extra output of this: lapply(split(dataset,dataset$trajectory),lfun) Is possible to eliminate any text output from an function? 2) I try to put an equation on a object to use in curve for example, but it don't work, it possible to make a object of an equation? ex. fx <- a + b*x for(a in 0){for(b in 1){curve(fx,...)}} 3) Exist in R any functions to estimate severals curves (non interactive) for a dataset? Something like table-curve 2d.
