Hi all, My apologies for a very simple question. I just downloaded R 2.6.0. I want to bring in all of the objects from 2.5.0 that I see when I type ls(). I have no idea how to do that. Thanks in advance.

Greetings, I'm interested in generating data from various bivariate or mulitivariate distributions (e.g. gamma, t, etc), where I can specify the parameter values, including the correlations among the variables. I haven't been able to dig anything up on the faq, but I probably missed something. A nudge in the right direction would be appreciated. David --

Hi, I'm plotting 5 autocorrelation plots on one page. Using par(mfrow=c(3,2)) everything comes out fine. However, for each plot, it prints a title on top of each plot that says Series followed by the variable name used in the plot. I want to suppress those titles, but I also want a general figure title on the bottom of the page. I've looked at the Murrell book as well as the acf

Hi all, I'm looking for a package that will estimate Markov models and provide transition probabilities. I'm not speaking of MCMM estimation packages.

I can't seem to figure out why I'm getting this error. The output is copied right off the screen. Notice how in some cases the back slash is missing. In other cases, it can't read a file that I know is there. Thanks in advance > library(foreign) > hrout <- read.spss("c:\\hrab200.sav") Error in read.spss("c:\\hrab200.sav") : unable to open file

Hi all, I'm looking for a contributed package that can provide a detailed account of missing data patterns and perhaps also provide imputation procedures, such as mean imputation or hot deck imputation and the like. Is there anything out there? Thanks in advance, David -- =========================================================================== David Kaplan, Ph.D. Professor

Hi all, I'm running White's test to correct for non-constant error variance and I am using the Anova function in the package CAR. My command structure is > Anova(scireg3, white.adjust="hc3") where scireg3 is an object from lm. I get the message "Error in SS[i] <- SS.term(names[i]) : nothing to replace with" What does this mean and how do I fix it. Thanks

Greetings all, I have two questions. I have a data set that is arranged in the example below. I wish to obtain a plot of the performance of each ID over Year on v1. It's not clear how I set this up? ID Year V1 1 1980 1 1 1981 2 1 1982 6 1 1983 4 2 1980 5 2 1981 5 2 1982 5 2 1983 6 Also,I would like to transpose the data to have the

Greetings all, I have two logistic plots coming from two calls to plogis. The code is .x <- seq(-7.6, 7.6, length=100) plot(.x, plogis(.x, location=0, scale=1), xlab="x", ylab="Density", main="Logistic Distribution: location = 0, scale = 1", type="l") abline(h=0, col="gray") .y <- seq(-7.6, 7.6, length=100) plot(.x, plogis(.x,

Let me try to be more specific. The x y coordinates are different because of NAs in the dataset. In this analysis, a set of hat values (a measure of influence in regression) is given for each observation. On the basis of the regression that was run to get these hat values, the sample size was 1164 (one removed due to NA). The length of the data set is 1165. If I remove the NA from the

Greetings, I'm trying to simply reorder a data frame on the row numbers. So, for example, instead of getting 1,2,3,4,5,6,7,8,9,10,11, ... 100 ..., I get instead 1, 10, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 11, ... I've tried commands such as df <- df[order(rownames(df)),] and and have substituted the order command with sort and sort.list to no avail. Any advice

Greetings all, I have three files that I would like to merge. The first is a student level file that contains the student ID, their school ID, and their country ID. The second is the school file that contains the school ID and country ID. The third is the country file with a country ID. I would like to merge the three together using the common country ID. Of course, what this would mean

Hi all, I'm looking for a program that will take the predicted probabilities from a logistic regression using glm{stats}, dichotomize them according to a threshold that I can control, and then use them to form sensitivity, specificity, false pos and false neg rates.
