Hi Mark,
Don't be the least bit sorry that I'm finding any of this hard to
understand. That's my problem. I ordered the Phil Spektor's "Data
Manipulation with R (Use R)" book last night as I realize I need to go
through some sort of training. Hopefully that will help clear up some
of my question
Hi. As I said in my first email, converting your data into a "long"
format makes a lot of sense. I'm sorry that you find it "hard ... to
understand why this would make plotting easier".
Wide format:
Subject ID, Experiment ID, humidity, light, whatever, T1, T2,T3,T4.
is much better rotated to

Yes,
First, select only columns C1 to C6, then look for values greater than 0,
after use this to select the columns in original subset.

I must admit I like this one. Pleasing to look at. It seems
approachable.
Try this:
subset(test[3,], select=C1:C6)[,subset(test[3,], select = C1:C6) > 0]
subset(test[6,], select=C1:C6)[,subset(test[6,], select = C1:C6) > 0]

Hi. Essentially your data is currently in "wide" format, with repeated
measures in different columns. For most analysis and in particular for
graphing, it is frequently helpful to reshape your data into a "long"
format, with one row per data value and additional variables to list
experiment or subj

OK, I guess I'm getting better at the data part of R. I wrote a
program outside of R this morning to dump a bunch of experimental
data. It's a sort of ragged array - about 700 rows and 400 columns,
but the amount of data in each column varies based on the length of
the experiment. The real data end
27 matches
