I have a data frame and want to append some text with all the elements of it.

For example

My Data frame

I want the resulting data frame as

number 1
number 2
number 3
number 4

So the "number" string is in common which I have to append with each elements of the dataframe. I am writing a for loop to iterate through the data frame but I do not know how to append "number" in each row.

Try `df1$myCol <- paste("number", df1$myCol)` – zx8754 Oct 20 '16 at 05:57
No that did not help.The dataframe is now coming like **number(1,2,3,4)** – priyanka3 Oct 20 '16 at 07:00

Try this toy example: `df1 <- data.frame(myCol = 1:4)` then run above code. It should work, if it didn't then please provide dummy dataframe of your own that is representative of your real data. – zx8754 Oct 20 '16 at 07:15
Yes it works perfectly.Thanks a lot. – priyanka3 Oct 20 '16 at 07:25
@zx8754 If I want to append something like number"one" 1 what can I do?I tried df1$myCol <- paste("number"one"", df1$myCol) and df1$myCol <- paste("number\"one"\", df1$myCol).Both did not work. – priyanka3 Oct 21 '16 at 02:21
