Hello All, I'm trying to print specific row and column for Observed_Scores matrix, however, when I execute the command "Observed_Scores[1,1]", I get the message "Error in Observed_Scores[1, 1] : incorrect number of dimensions". Could you please help and let me know where is the mistake? Here is my program: library(ltm) library(psych) # Settting the working directory

Hi All, I'm generating 10 different data sets with 1 and 0 in a matrix form and writing the output in separate files. Now I need to stack all these data sets in one vector and I know that stack only operates on list or data frame however I got these data sets by converting list to a matrix so can't go backwards now. Is there a way i can still use Stack? Please see the program:

Hi,  I want to do regression in each group. I made the group the following way. Now I want to run regression in each of the three groups.. Suppose , x<-c(0.5578196,6.5411662,13.2728619,2.0217271,6.7216176,3.37220617,2.5773252,7.2600583,15.3731026,3.4140288,8.1335874,     15..6476637,4.3014084,9.1224379,18.5605355,4.7448394,11.9296663,18.5866354,12.3797674,18.7572812,2.70433816,2.88924220,

Dear all: Does anybody know about label conflicts between xtable and Hmisc? I found a couple of e-mails similar to this problem but is not clear to me how to get around the label problem. The first table(longtable below) is generated with the latex function from Hmisc but for some reason when I try to hyperlink to it,it takes me to the top of the document. The second table created with the xtable

Hi, Can any one please explain why the following code doesn't work? Or can anyone suggest an alternative. Suppose       x<-c(23,67,2,87,9,63,8,2,35,6,91,41,22,3)        mat<-0;        for(j in 1:length(x))        {              for(i in 1:p)                      mat[i,j]<-x[j]^i;        }    Actually I want to have a matrix with p columns such that each column will have the

Hi: Could someone try to run this example? I can't make it work. ## Not run: \begin{small} \setlongtables \begin{longtable}{ <<results=tex,fig=FALSE>>= cat(paste(c('c', rep('cc', 34/2-1), 'c'), collapse='@{\hspace{2pt}}')) @ } \hline \endhead \hline \endfoot <<results=tex,fig=FALSE>>= library(xtable) set.seed(2345) res

Hi, attached follows a patch to add a feature that I think it would be useful having in the print.xtable function of the xtable package. It adds the option 'tabular.environment' to that function, which could be used to set an alternative tabular environment, as the name already suggests. This is particulary useful when dealing with long tables, which do not fit in a single page. In the

Dear list, I'm using the Sweave function in order to get some report. Here one chunk: <<echo=F,results=tex>>= report<-lapply(repor, function(x) { (print(xtable(data.frame(x[1:2,]), align="|l|rrr|"),floating=FALSE,tabular. environment="longtable",include.colnames=FALSE,size="\\small"))

Hi: I need to do text mining on PDF files. I understand there is a readPDF command in tm that can be used. Have read the 2008 posts on converting PDF files to text by Tony Breyal and others. Wondering if the procedure has been standardized in any tutorial or otherwise? Being new to R, I was able to follow only part of the discussion. Any way to get a set of step by step instructions

Dear All, I am trying to simulate data for a spline/piecewise regression model. I am missing something fundamental in my simulation procedure because when I try to fit my simulated data using the Gauss-Newton method in SAS, I am getting some wacky parameter estimates. Can anyone please check my simulation code and tell me what mistake I am making in generating data for spline model? Thank you

Hi: I am going through some of the xtable examples and I can't make the one below work. I need to create a longtable on the fly keeping the column headers for all the pages and I thought this example could give some ideas on how to do it. I am using Sweave and xtable to create my tables and graphics. I wonder if someone could tell me what's wrong. Thanks ## Not run: \begin{small}

Hi, I'm trying to convert Matrix into a list format and have written the following code: path = ("C:/2PL_Alpha_C_2PL_Loading") setwd(path) getwd() congeneric = matrix(rep(NA,36),nrow=6,ncol=6) conFirst = matrix(rep(NA,36),nrow=6,ncol=6) conFirstTwenty = rep(NA, 20) k = 1 #Reading all the Alpha and Congeneric 2PL values into variables alpha <-

I have been using the xtable package to export great latex tables and am very pleased with the package. Is there a way to modify the format of the tables: (1) some of my tables are to long to fit on a single page. I would like to modify the xtable to produce a longtable compatible with the longtable.sty in latex. Are these modifications possible and if so where are they documented? (2) Is it

An alternative solution that allows you to break it down by categories is in the functions below. Comments/suggestions welcome and encouraged. Note that much thanks is due to those who responded to an earlier post of mine on a similar topic. To use (assuming you have a data.frame falled pathDist with columns distances (your numeric data of interest), Capacity, Surface, and SITE (vectors of

Hi: I need help merging rows. I am trying to merge the 'Month' column using \multirow. For example for the column 'Week' I want July to be merged into one row(weeks 27,28,29,30) and so on for the following weeks. Below, I am creating a PDF using Sweave, MikTex,R-2.8.1 and windows XP to show an example. \documentclass[11pt]{article} \usepackage{longtable,verbatim} \title{How to

Hello R-devel, I am currently attempting to implement an API similar to data.table wherein single bracket subsetting can accept an unquoted expression to be evaluated in the context of my object. A simple example from the data.table package looks like this: DT <- data.table(col1 = c('a', 'b', 'c'), col2 = c('x', 'y', 'z')) DT[col1 ==
