non-SQL sqlQuery error
...gives this:
5: stop("not all specified columns exist")
4: "[.data.frame"(data, , )
3: data[, ]
2: sqlGetResults(channel, errors = errors, ...)
1: sqlQuery(con.object, " ... long query here ... ")
The puzzling thing is that the error does not seem to be like the usual
mispecified-SQL type that I normally

since I can't really see what's going on

data layout for crossed factors w/interaction in linear mix models
...rom Y = XBeta +Zb. That is, using the same first two columns as above, but substituting 1020 columns (10 for ai's, 10 for bj's and 100 for abij's) for the last three columns.
I get the message: "Error in eval(predvars, data, env) : invalid envir argument"
Is my data layout mispecified? Do I need to input initial values for the random components in order to get the REML estimates? I lmer valid for unbalanced designs? Any help would be greatly appreciated.
