Dotchart per groups
Hi all,
I would like to ask you for help. I did a dotplot - using dotchart
function.
There are two localites (loc) with values 75 or 56 in my data ZZ.
The f column has 4 levels: P1, S1, S8, R6.
The dataframe is ordered by N value, pchloc value is assign to use "pch" in
plot.

Using data frames for EDA: Insert, Change name, delete columns? (Newcomer's question)
I am finding complex analyses easier than some elementary operations in
R. In particular I want to do some low level exploratory data analyses
with data in a data frame but cannot find commands to easily insert,
remove (delete), rename, and re-order (arbitrarily, not sort) columns.
I see that the micEcon package has an insertCol command, but that is for
matrices, not data frames. I have looked
