Hello all! I have a code in R which basically opens, saves and closes all excel sheets in a given directory. The code is following:
----------------------------------------- R code start ------------------------------------------ normal_update <- function() { # Updating files in main directory Dir <- choose.dir() setwd(Dir) library(RDCOMClient) library(SWinTypeLibs) ex = COMCreate("Excel.Application") Files <- list.files()[grep(".xls",list.files())] n <- length(Files) # Choose an add in to load into excel add_in <- file.choose() for(i in 1:n) { # ex = COMCreate("Excel.Application") addin = ex$Workbooks()$Open(add_in) book = ex$Workbooks()$Open(paste(c(getwd(), "/", Files[i]), collapse = "")) # shell(paste("ECHO Y | DEL", '"C:\\Dokumente und Einstellungen\\Praktikant1\\Eigene Dateien\\RESUME.XLW"')) ex$Save() book$Close() rm(list = c("book", "addin")) } } ----------------------------------------- R code end ------------------------------------------ The algorithm is: - the first setwd sets the desired directory (in my case I need only the above one) - create an Excel instance - get all the files with the ending .xls* - start loop: -- load the addin into excel -- open the i-th excel file -- save excel -- close the excel book (not the whole excel, just the book which is open) -- clean up the files The problem: After the first iteration of the for-loop, when the code tries to save and close the file I get the error message Browse[1]> i debug: 2 ... debug: ex$Save() Browse[1]> Fehler in .COM(x, name, ...) : Cannot locate 0 name(s) Save in COM object (status = -2147418111) What is the reason for this problem and how can I bypass it?
