title: R reading Excel files with carriage returns
body: <p>I create a routine in R to import multiple Excel files that I need to merge in one big txt file. I use the read.xls function. Some of these xls files have carriage returns in cells ("\n"). Then, when I write the txt files (write.table) R interpret this "\n" as new lines.
  How can I clean the xls files or read properly them to remove the not necessary "\n"?</p>
  
  <p>Thanks!</p>
