Reshape dataframe according to ordered variables
Dear all,
I am still a R apprentice... Apologies for the basic question.
I am trying to reshape a dataframe based on the order of two variables
(a character variable and a numerical variable). To simplify it,
consider the following dataframe
> df<-data.frame(id=c("b","b","a","a","a"),ord=c(2,1,1,3,2))
id ord
1 b 2
2 b 1
3 a 1

Latin Hypercube Sampling with a condition
Hello all,
I am trying to do a Latin Hypercube Sampling (LHS) to a 5-parameter
design matrix. I start as follows:
library(lhs)
p1<-randomLHS(1000, 5)
If I check the distribution of each parameter (column), they are
perfectly uniformly distributed (as expected).For example,
hist(p1[,1])
Now the hard (maybe strange) question. I want the combination of the
first three parameters to sum up to

problem with function "Truncate" in package "distr"
Hello all,
Can someone tell me why the following mixture of two log-normal
distributions does not get truncated? What puzzles me is that the
function works almost always, but for certain combinations (like the
one below), it does not.
# R code example
library(distr)
mix<-UnivarMixingDistribution(Lnorm(3.2,0.5),Lnorm(5.4,0.6),mixCoeff=c(0.3,0.7))

extract printed value from a function
Hello all,
This shouldn't be difficult, but I am not able to extract a printed
value from a function and assign it to an object.
In my case,

> twotPermutation(c(2,3,4),c(3,6,5),plotit=F)
[1] 0.298
I would like to assign this result to an object.
Thanks,

barplot2 x-axis
Dear R users,
I am trying to build a barplot2 graph however I can't find a way of defining
the scale for the x-axis.
I would like to show in my x-axis only the numbers 0, 25, 50, 75 etc. (so
far R is giving me a random scale hard to interpret and it doens't look
nice...). Could anyone advise me on how to do this please, it would be a
great help! Thank you.

Sequence for repeated numbers
Hello fellows,
I would like to create a sequence for repeated numbers in a dataset. For

unorder an ordered factor
Given an ordered factor, how does one unorder it?
I tried various commands with reorder, with order=F, but they all gave me
error messages. I also tried to drop the order with various 'as dot
something' commands, but these didn't work either.

PLS regression?
Hi all,
I would like to do some QSAR analysis (quantitative structure activity
relationship). I need to use some Partial Least Squares (PLS) regression,
but I have not seen this option on the R-project. Is it possible to do this
kind of regression on R?
thank you in advance

Contrasts for ordered factors
Dear all,
I do not seem to grasp how contrasts are set for ordered factors. Perhaps someone can elighten me?
When I work with ordered factors, I would often like to be able to reduce the used polynomial to a simpler one (where possible). Thus, I would like to explicetly code the polynomial but ideally, the intial model (thus, the full polynomial) would be identical to one with an ordered factor.

UTMP duplicated entries
Hi everybody!
I've been noticing some strange entries in samba/utmp. I have a lot of
00:00 timed sessions.
But the worst problem is that i found some conflicting information. Since
windows doesn't allow concurrent login sessions, I think utmp should not
have generated the following entries.
