You state that you want "$$$" as the separator, but your example has "$$" and "$" so I'm assuming an indeterminate number of consecutive $. x <- c("qwer$$12$$qwre", "ewrtr$7789$ewwe") x <- strsplit(x, "\\$+") x <- do.call(rbind, x) x <- data.frame(x, stringsAsFactors = FALSE) x$X2 <- as.numeric(x

[R] wrong data interpretation in R

Hi, maybe somebody would be kind enough to help a bloody and unprofessional beginner like me (and I hope I did not overlook the answer to my question on the website). I've imported a csv data frame into R, but I can't run a regression because R interprets 4 out of 5 variables as factors (rather th

Re: [R] puzzling RODBC error

It seems that your sqlTables also give no results. So there must be something wrong with the ODBC connect. I didn't use odbcConnectAccess, but made an ODBC connection, and then used ODBCconnect to connect to our database. Maybe you can define a user DSN and try it this way? Bart -- View this
