...command ! What should i do to recode i.e. the values 9,99 & 999 to NA. Something like this x <- c(9,99,999,NA) x==NA ...do not what i want, because the data.frame show the values 9,99 & 999 and not NA in this fields ? P.S. Perhaps is it easier to define all Missing Values in SPSS to SYSMIS so that i have got a blank and R automatically define's NA to the blanks ??? Best thanks for advance and regards, christian _______________________________________________________________________ 1.000.000 DM gewinnen - kostenlos tippen - http://millionenklick.web.de IhrName at web.d...

...re always ignored). Is there any way in R to find out if any value was user-defined missing in Spss or not? Even to keep the information as an attribute would suit me fine, or to keep them as a string character like "miss" would be even better. To transform them into "NA" as the sysmis data from Spss is transformed automatically, would be an other alternative. Unfortunately I don't know if any of these options are possible. Could you help me out? Many thanks. Christine Christmann --

Hi, I am still new to R and have a programming question. I have created a small function which takes a parameter. In the function I want to be able to refer to the names of the variables sent to the function (specifically I want to be able to use the name of the variable given to the function in an output table). For example, in the following (fictional) function I want some way of printing

Dear List, I apologize in advance if this is silly. I tried to replicate an analysis I did previously in SPSS using R, and was surprised to find different results. So my question is: shouldn't the following SPSS syntax REGRESSION DEPENDENT INC89 /METHOD=ENTER hiedyrs experien SE93rec. Yeld the same results of the following R command modelB<-lm(INC89~HIEDYRS+EXPERIEN+SE93REC) I

A friend of mine recently mentioned that he had painlessly imported a data file with 8 columns and 500,000 rows into matlab. When I tried the same thing in R (both Unix and Windows variants) I had little success. The Windows version hung for a very long time, until I eventually more or less ran out of virtual memory; I tried to set the proper memory allocations for the Unix version, but it never
