I used in 2004 an earlier version of R (1.6.0 ?) for quantile regressions

 

Now I downloaded version 2.5.1-win32 and I cannot A) read my old files (Our
exel working space was saved in csv) and also the series of instructions
does not work, see below (B) rq function is not recognized)

 

filename <- read.csv("filename.csv",header=TRUE,row.names=1)

fit95 <-rq(y~a+b,data=filename,tau=.95)

 

 

Thanks in advance
