Add additional text to string

How do I add the additional text p= before the values in the data frame? Do you use gsub?

   Seqbuster_Filter_MM_miR21_5p$FDR

3                      3.233019e-17
4                      4.800951e-22

It is more natural to use paste or sprintf

 pvaluemir21[,1] <- paste('p =', pvaluemir21[,1])

Or

 pvaluemir21[,1] <- sprintf('p = %f', pvaluemir21[,1])

But sub can be used

 pvaluemir21[,1] <- sub('(.*)', 'p=\\1', pvaluesmir21[,1])
