You made the same error as the first time - a misplaced parenthesis.
Make the last 2 lines
.Names = c("row", "stimulation", "positivity", "group", "copy")),
row.names=c(NA, 120L), class="data.frame")
instead of
.Names = c("row", "stimulation", "positivity", "group", "copy"),
row.names = c(NA, -120L)), class = "data.frame")
The proper code makes row.names an attribute of the list containing
the columns, the bad code makes it another column and makes a
data.frame with no row names.
