Hello all,
I have an outstanding request to documents units [1] or other variable-specific
facts in data files. I am thinking in particular of tab-delimited files that
are suitable to be read into a data frame. One suggestion/request is to add a
line of text under the column headings.

A while back I asked about getting a list of points that R considers
influential after fitting a linear model, and very quickly got a helpful
pointer to influence.measures(). But "it has happened again." The trouble I
am having is that points marked on plots are not flagged in the output from

Hello all,
I fit a linear model to some data and used plot() to create diagnostic plots
for the fit; I am having trouble reading the points that R is flagging as
influential. Is there a way to get the list of influential points from the fit
or its summary, etc.? Most likely, there are a few p

Hello all,
I had a very strange looking problem that turned out to be due to unexpected
(by me at least) format changes to one of my data files. We have a small lab
study in which each run is represented by a row in a tab-delimited file; each
row identifies a repetition of the experiment and a

Hello all,
I am loading a data frame, fitting a model, getting diagnostic plots and they

re-fit without them.
After I delete an offending row (identified by one of the diagnostic plots),

Hello all,
I think I probably did something stupid, and R's part was to allow me to do it.
My goal was to control the order of factor levels appearing horizontally on a
boxplot. Enter search engines and perhaps some creative stupidity on my part,
and I came up with the following:
