TIBCO Enterprise Runtime for R returned an error (21)

The data function 'Evolution' could not be executed.

Error in aggregate.data.frame(x, ...) : no rows to aggregate

eval(script, envir = .GlobalEnv)

eval(script, envir = .GlobalEnv)

withCallingHandlers({

aggregate(dfin$"volume", by = list(month = dfin$date), FUN = function(x) sum(x,

aggregate.default(dfin$"volume", by = list(month = dfin$date),

aggregate.data.frame(x, ...)

stop("no rows to aggregate")

Is this still an open question or did you solve it

 

What looks a little bit strange to me is dfin$"volume". Here, I would expect dfin$volume (without the quotes). "volumne" doesn't look like a valid column name.
