The output from
str(tdf)
class(tdf)
would be helpful.
It may be that "td.data.frame" objects, whatever they are, do not use the
same syntax as "data.frame" objects. Perhaps they only support numeric
indexing, not logical indexing.
Assuming logical indexes are valid for td.data.frame objects,
tdf$Dias_Mora
should be
tdf$dias_mora
[see the variable names shown in the output of summary()]
If that doesn't fix it, then try this:
tmp <- df$Dias_Mora > Dias_Mora &
tdf$periodo >= Fecha_Inicio_YM &
tdf$periodo <= Fecha_Final_YM &
tdf$tipo_id == 3
Then, one or more of these should help reveal the problem:
class(tmp)
str(tmp)
table(tmp)
tmp should be logical, and should not have any NA (missing) values
All of this assumes that
Dias_Mora
Fecha_Inicio_YM
Fecha_Final_YM
all exist and are of the correct type (apparently numeric)
Also, please do not post in HTML. And you should identify what package
td.data.frame comes from, since it is not part of base R.
