Generally that mean you need to specify the levels of a factor
variable to suit your expectations of ordering.

Nope. Nothing attached. Please review the answers given earlier today
regarding attachments. Specifically .csv files are not mention as
acceptable in the Posting Guide and are in fact scrubbed by the mail
server. That does not mean that commas cannot be used as a separator,
but the extension needs to be ".txt". (Machines are very, very literal.)
df <- read.csv(file = "T_5-04b_LTC-SE-SO-Compared.csv")
So no one will be able to proceed.

# Basic default plot (correct data, incorrect layout):

as.table = TRUE,
data = df,

Thanks for all the help.
