Newbie question: Converting Table
...and I have searched helpfiles and this forum on my 2
questions. Hope you guys can help me out! :-)
Many thanks in advance!
Cheers,
Lars
Q1: I imported a csv file with columnames subject and class. There are about
1000 different classes...
It looks like this:
subject1, class1
subject1, class2
subject2, class1
subject2, class3
...
subject999, class1
subject999, class2
Now I want to transform this in R into a table (with columnnames
subject,class1,class2,...) like:
subject1, yes, yes, no, ...
subject2, yes, no, yes, ...
...
Q2: I want to count the matching class patterns in the previous table

simple ts.plot question
*Respected Sir,
I have a simple question regarding plots of time series in R.
I have to plot "conc" against "time" **for each individual and display in
the same panel for the in-built dataset "Indometh" in R.
*
***I have six time series, say subject1.ts, subject2.ts, .............,
subject6.ts.
The observations are taken at an interval of 0.25 hr.
All of the series ranges from 0.25hr to 8.00 hr.
How can I plot all the six time series in the same panel**?*
*I am eagerly waiting for your reply. Thanks in advance.*

Calculating the correlations of nested random effects in lme4
...and then again I have values for each subject in
group 0 (intercept column) and group 1(Group1 column). The same is with
slope. What does this data show me?
What is the difference between defining random factors as
`1+RT|Group:subject` and then looking at Intercept and RT values for
0:subject1, 0:subject2...., 1:subject1, 1:subject2...
and
defining random factors as `RT*Group|subject` and looking at the various
columns (Intercept, RT, Group1, RT:Group1) for subject1, subject 2 etc.?
Thank you,
Dominik
