dear steve,
thanks for replying. actually i am trying to open an excel file containing 16 sheets by the following command
>library(XLConnect)>sheets <- list()>for(i in 1:6) {>sheets[[i]] <- readWorksheetFromFile("DPI.xlsx", sheet=i,region="A1:N1160")>}
and all i m getting is the error i described earlier. my system has a RAM of 4gb. yes, i have increased the value of Xmx to 1gb. the output of my session info isR version 2.15.2 (2012-10-26)
Platform: i386-w64-mingw32/i386 (32-bit)regardselisa
