Thanks a lot to both of you for the effort and nice suggestions.
I have tested all suggested coding variants and I do succeed in changing the
data structure, for example like this (with a test using str())

I’d appreciate your help on understanding the following.
It is not very clear to me from the model.matrix documentation, why simply
changing the order of terms in the formula may change the number of resulting
columns. Please note I’m purposely not including main effects in the model
formula i
This does seem to be a good situation for ordinal regression. The R rms
package's orm function allows for thousands of categories in Y. But it
doesn't handle censoring.
This discussion would be better for stats.stackexchange.com

Hi Jim,
Thanks a lot! It works now. I didn't remember how to access the
datetimes in w10min. names(...) is the solution!

Thanks, Thierry & Duncan. I'll go down the survival analysis route.
The data are for central American epiphytes, so not your usual
species. Visually there's definitely differences in the times of
germination, but not in eventual germination, so that's
straightforward.

I have a list of strings of different lengths and would like to split each
string by underscore "_"
pc_m2_45_ssp3_wheat
pc_m2_45_ssp3_wheat
ssp3_maize
m2_wheat
I would like to separate each part of the string into different columns
such as
pc m2 45 ssp3 wheat
But because of the different length
Try this:
mylist <- list("pc_m2_45_ssp3_wheat", "pc_m2_45_ssp3_wheat", "ssp3_maize",
"m2_wheat")
mylist <- lapply(mylist, function(x) unlist(strsplit(x, split="_")))
allstrings <- unique(unlist(mylist))
lapply(mylist, function(x) allstrings[match(allstrings, x)])
[[1]]
[1] "pc""m2""45"
Hello Pradeep
I downloaded divorce.dat but I could not find tabs between the columns.
You defined tab as separator, so your columns should be separated by tabs.
Therefore read.table reads the whole first line and wants to save the
result as numeric because you defined the first column as numeric
Hi Pradeep,
Any software would be challenged to determine the boundaries between your
columns.

This is not a tab delimited file (as you apparently assume given the
code), but a fixed width format, hence I'd try:

widths <- c(9, 13, 10, 8, 10, 6)
f5 <- read.fwf(url, widths = widths, skip = 1, strip.white = TRUE)

A Big thanks to everyone to help me solve this problem .
My bad I assumed the file is delimited by tab which it was not . Its a
fixed width file and the code that Uwe gave is just perfect .
It was cleaver to skip the first row since the delimiter cannot be
specified in this case .I added few more t

Dear Rolf,
I'll take a look how to fix it tomorrow, your proposal is very welocme,
of course,

Hi
I use Sweave and some tikz in latex but not in Sweave
Your problem is that you left out Sweave in the preamble
It must be in the preamble of any Sweave document
I added sizing so that it is not off the page.
I do not know if Sweave options will cover this or you have to set it.
eg
\setkeys
