Hi, I am trying to use (i) as an index but R considers it as a function and not as text. To be more specific I would like for example to estimate some regressions named qrnox1, qrnox2, qrnox3,..... and so on. But when I am using qrnox(i) ot qrnox[i] it tries to find the ith element of vector qrnox. The thing is that I want to estimate the qrnoxi regression and not the qrnox(i) function or whatever. Even if I create a vector text as elements like qrnox<-c("qrnox1", "qrnox2", "qrnox3", .....). It doesn't work either. Is there any way to do it ? I have post the part of the code
Thanks Dimitris ####################################################### quant<-c(0.25, 0.5, 0.75) qrnox<-c("qrnox1", "qrnox2", "qrnox3") for (i in 1:3){ qrnox[i]<-rq(nox~factor(year)+factor(state)+pcinc+I(pcinc^2)+I(pcinc^3), tau=quant[i], data=exmp) } summary(qrnox1) -- View this message in context: http://www.nabble.com/Problem-to-male-an-Index-in-looping-tp19706138p19706138.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
