No example. You are a regular now and examples ARE requested.
Would have thought something along the lines of:
pvh[ unlist( apply(pvh, 1, function(x) "dnv" %in%
as.character(x) ) ) , ]
Not sure if the unlist or as.character are really needed because ...
no example on which to test.

Hi R-helpers,
I'm trying to use this code
pvh_dnv<-pvh[sapply(pvh=="dnv"),]
to make a new dataframe containing the rows from pvh that contain the
value of "dnv" in ANY column.
But, it's not working. I get this error
Error in match.fun(FUN) : element 1 is empty;
the part of the args list of 'is.function' being evaluated was:
(FUN)
which, to me, is cryptic.
I'd appreciate any help you might provide, thanks!
