I get the same error on a Mac in an English locale. I'm afraid the code in the
offending function `.getTne` appears somewhat cobbled together. When I try to
debug, I get a single row, 1920 column matrix for n1 which is numeric with all
entries == 1. Object `t1` cannot be found.
{
s <- Es <- .SD <- NULL
n1 <- names(dt1)
f1 <- function(x) paste(dQuote(paste(x, "=", sep = "")),
", get(", dQuote(x), ")", sep = "")
t1 <- paste(sapply(n1, f1), sep = ",")
if (length(t1) > 1) {
t1[2:length(t1)] <- sub("\"", "\"_", t1[2:length(t1)],
fixed = TRUE)
}
t1 <- paste(t1, collapse = ",")
t2 <- paste("paste(", t1, ", sep='')")
# next line throw the error.
p1 <- parse(text = t2)
q <- quote(eval(p1))
dt1[, `:=`("s", as.factor(eval(q, envir = .SD)))]
stopifnot(attr(model.response(mf), "type") == "right")
y <- data.table(unclass(model.response(mf, "numeric")))
I'm afraid I have been o help.
