Dear R users,
I need to merge two data frames based on both equal and unequal comparisons.
The "sqldf" package used to work well , but today, I cannot resolve the
following error by reinstallation of the sqldf package. Can anyone suggest a
different way to perform this kind of merge function?
Thank you,
Ding

> DMS_log2pbde47 as b
+ on a.chrom = b.chromosome and a.start <= b.MAPINFO
and a.end >= b.MAPINFO" )
Error in get(as.character(FUN), mode = "function", envir = envir) :
object 'as.AsIs' of mode 'function' was not found
