This reminds me of a request I have been meaning to make. S-plus time series functions normally use only the longest contiguous portion of the series with no missing values. I think a good way to implement this would be to have an "na.omit" method for time series, but this isn't a generic function in R (It is in SPLUS 3.3). Could this be changed? -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel 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 !)
