The code write.table(x, "clipboard", sep="\t") will copy a table x to the clipboard in such a way that it can be pasted into Excel preserving the table structure. The functions above only work with columns of data rows are combined into single entries. It could be used to paste a column of numbers copied from other applications, such as Word or Notepad. The function scan() is not limited to Excel. To copy a row from Excel, first transpose the row in Excel, then copy the result as a column. For example, if you copy horizontally adjacent cells containing 19 and 44 and run x <- scan(), then x will contain 1944. If you copy a row of numbers from Excel and call scan, the numbers will be concatenated into a single number in R. Note that scan works with columns in Excel. If there is an empty cell, only the numbers above the first empty cell will be copied into the R vector. R will produce an error message if the copied column contained a string. Note that scan only works with columns of numbers. Then x will contain the numbers from Excel as numbers, not as quoted strings. Copy the column from Excel, run x <- scan(), type Ctrl-v to paste into R, and press enter to signal the end of input to scan. You can use the scan function to copy a column of numbers from Excel to R. If you select a block of numbers from Excel, each row becomes a single string containing tabs where there were originally cell boundaries. The elements will be character strings, even if the clipboard contained a column of numbers before the readClipboard command was executed. Will assign the contents of the clipboard to the vector x. The companion function for writeClipboard is readClipboard. After a vector has been copied to the clipboard, the elements of the vector will be separated by newlines when pasted into a document. If one element of a vector is a character string, all elements will be cast to strings without the need for an explicit as.character statement. The solution is to call writeClipboard( as.character(x) ), casting the object x to a character string.Īll variables in R are vectors, and elements of a vector can have differing types. Produces the error message Error in writeClipboard(str, format) :Īrgument must be a character vector or a raw vector For example the code > x writeClipboard(x)Ĭopies the string “hello world” to the clipboard as expected. However, the argument to writeClipboard may need to be cast to a character type. R has a function writeClipboard that does what the name implies.
