Dear R community,
Package bit version 1.1-3 and ff version 2.1.2 is available on CRAN and should

It adds convenient utilities for managing ff objects and files (see ?ffsave)

Hi, all
I have a question on mgcv and ns. Now I want to compare the results from

In order to confirm the result from glm1 is consistent to those from gam

Notice that 'nc' is multivalued (nc<-x$Label[61:308]). If you want to
check if x$Label[i] is one of the values in 'nc', then use %in%:

The error happens because 'if' can only have a single conditional
