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 4

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

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))

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, > library(DAAG) > 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, Duarte

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. Below I show the code I have

hi All I updated my wine ot RC1 and run winecfg then I have some strange line Code: err:winedevice:ServiceMain driver L"sptd" failed to load all work but what it can mean?

Hello fellows, I would like to create a sequence for repeated numbers in a dataset. For example: ID <- c(1:20) grade <- c(4,4,4,5,5,7,7,7,7,8,8,8,9,9,9,9,9,10,10,10) Data: ID Grade 1 4 2 4 3 4 4 5 5 5 6 7 7 7 8 7 9 7 (...) I would like to create a variable "sequence": Data: ID Grade Sequence: 1 4 1 2 4 2 3 4 3 4 5

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. -- View this message in context: http://n4.nabble.com/unorder-an-ordered-factor-tp2014745p2014745.html Sent from the R help mailing list archive

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 best regards, olivier [[alternate HTML version deleted]]

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.

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. liana smb/2 192.168.0.207 Fri Sep 2 18:43 - 00:52 (06:08) rodrigobaso

Dear R helpers, I'm trying to recode an ordered factor to reverse its scale, but I can't figure out how to make it. I am using the Recode function provided by the Car package. I've created an ordered variable: data$o.var1 <- ordered(data$var1, levels=c(1,2,3,4), labels =c("very satisfied", "fairly satisfied", "not very satisfied", "not at all
