When using RPostgreSQL I find that I cannot use sqldf in the same way. For example if I load the library and read in data into a data frame using t
RPostgreSQL
sqldf
I had the same error and I detached the RPostgeSQL package, rerun my sqldf code and it worked fine r detach("package:RPostgreSQL", unload=TRUE)
r detach("package:RPostgreSQL", unload=TRUE)
