Dear Raj,

Hi!
Nice example!
You just need to learn about the functions names() and paste():
names(dff)[1:6] <- paste("bp", 1:6, sep="_")

Read the help page for the names function:
?names
... note particularly the examples section.
You might also find the fact that the paste0 function works on vectors to be
helpful:
paste0( "bp_", 1:6 )
