Deleting observations - can't see the data after that
Hello all,
I am loading a data frame, fitting a model, getting diagnostic plots and they are flagging a couple of observations as problematic. Fair enough, and I want re-fit without them.
After I delete an offending row (identified by one of the diagnostic plots), something like
data = data[-3,];
then R will no longer print the contents of the data frame; it tells me it is a data frame

[OT] (slightly) - OpenOffice Calc and text files
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 associates it with some subjective measurements and times from our notes that get used to index another

plot(aModel) vs. influence.measures()
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 influence.measures(), and I can't read them on the plots. I tried some successive

Ordering categories on a boxplot - a serious trap??
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:
v=read.table("factor-order.txt",header=TRUE);
levels(v$doseGroup) = c("L", "M",
