Hello R friends, I want to use my R script in VB to make macro in Excel. I tried with RExcel but it seems to me that this package is just GUI API and I still have to run(connect) R to use the script.

Hi All, I have conducted the following survival analysis which appears to be OK (thanks BRipley for solving my earlier problem). > surv.mod1 <- survreg( Surv(timep1, relall6)~randgrpc, data=Dataset, dist="weibull", scale = 1) > summary(surv.mod1) Call: survreg(formula = Surv(timep1, relall6) ~ randgrpc, data = Dataset, dist = "weibull", scale = 1)

Dear All, How do I read in multiple data frames or matrices in a loop, e.g. for (i in 1:n) { channel <- odbcConnectExcel("filenames") file[i] <- as.data.frame(sqlFetch(channel, "sheet")) } I would like file[i] to be the name of the data.frame (i.e. file[1], file[2], file[3],...etc) rather than a vector. Thanks in advance for any help. Dave

Hello, it seems that the main results of survival analysis with package survival are shown only as side effects of the print method.
