Hello,
I am new to amelia and have been unable to find any info on the error I am
receiving:
*> tscsPlot(bd.am.poly1, cs = "Fraud", var = "n")*
*Error: Unsupported use of matrix or array for column indexing*
The data is 3 variables: a date var used for the ts, a grouping var used
for cs, and a count var, "n", which is my outcome variable that requries
imputation.
My initial amelia call looks like this (note that it wasn't clear if amelia
supported datetime objects, so I converted to seconds since epoch - if it
can handle datetime objects and this conversion is unnecessary, it would be
great to know that!):
*>bd.am.poly1 <- amelia(bdsum, idvars = "date", ts = "datenum", cs =
"call.type", polytime = 1, intercs = T)*
Here's a sample of the data:
date call.type n datenum
<date> <fctr> <dbl> <dbl>
1 2016-08-17 Criminal Mis C NA 17030
