Macros in R

I like a short help file:

helpSql <- function() { print("Four Column query") print("View: any equ or and or2 and3 or3 echo ") print("q4('qx, text1 text2 text3')") print("qf() list known databases from keybase") print(" qr('sql text',database)") print("qd - exact selection of data in database") print(" qd('series_id',database)") print("q2 - two col seriesid search") print(" q2('qx w1 w2 w3',database)") print("qa 2col search database list"); "Done" }
