Dear list - I just discovered to my surprise that I cannot define a function with an argument named 'break' or 'while'! 'breaks' is okay. Maybe this is no surprise to the R developers. R-1.7.1, 2003-06-16...

? "concatener" ? Transliterated, this suggests the function rbind(). The function merge() does something very special. If rbind() will do what you want, it might be much faster. - tom blackwell - u michigan medical school - ann arbor - On Wed, 16 Apr 2003, Erwan...

Make it three separate functions. This gives an example of how argument passing works. > Pdig <- function(nlinhas) { > Tdig <- (15.50 + 7.45*nlinhas); > (3*(Tdig*(30/3600))+1*(30*(30/3600))); > } > Ldig <- function(nlinhas) { > Tdig <- (30.50 + 7.45*nlinhas...

Dear r-help - I just noticed that in my R-1.7.1 on i386-pc-linux-gnu, the page displayed by help("print") ends with the line " ## Printing of factors illustrated for ex" and then no more. It looks...

What function "simint()" ? At least using R 1.6.1 (Redhat linux), help.search("simint") returns "No help files found ...". Also, it's no surprise that na.omit() might omit rows with NA's but then NOT purge the levels...
