'Combine cells in the first row

can somebody help me?

This is my actual data_frame

and this is what I'd want to get

Is there a way to combine only the cells in the first row in R?

I was trying to do it in excel one by one but I've more than 6000 columns so it takes me ages!

Thank you for your help!

You could collapse all the cells in the fist row into one cell and leave the others empty. If x is your data frame:

x[1,] <- c(paste(x[1,], collapse=""), rep("", ncol(x)-1))
