Hello, I am having trouble reading an spss file into R. I have reset my working directory to the folder where this file is stored. This is what I've typed into R and the error message I received: + getwd() [1] "/Users/daviacox/Graduate School/PLS 801" > read.spss("norwil.spss") Error in read.spss("norwil.spss") : error reading portable-file dictionary

I am using the read.table function to load an Excel data set into R. It has a few variables with very long qualitative (free response typically in sentences) response that I would like to keep, but would like to limit the "length" of the response that R shows. Is there some sort of string or column width command I can include in the read.table function to limit the length of words used

I have been trying to install the new, patched R 2.1.0a along with the Rcmdr on my mac. I got the basic R package installed, but in Project Manager, the tcltk package will not install. When I downloaded the Rcmdr binary package from the Berkeley site, it did not show up on the package installer list until a second attempt, but it still does not show up on the package manager list. On

Hello, I have a problem that I am trying to solve and I am not sure how to do it in R. Suppose, that 16 numbers are choosen at random from 0 to 9, what's the probability that their average will be between 4 and 6. I typed the following code: set.seed(100) sample(0:9, 16, replace =TRUE) [1] 3 2 5 0 4 4 8 3 5 1 6 8 2 3 7 6 Is what I got, however I realize the set.seed function

Hello, I have installed R on my Apple Laptop. Next I wanted to install the package Rcmdr which requires the package tcltk.

Hello everyone, i have been searching the whole day, trying ANY solution offered by the internet and before headbanging against the wall would like to try asking for your help. As many others, i am haveing problems loading the Rcmdr package with Macbook running Tiger 10.4.11. X11 version updated to the last one after having manually installed.

Hello, Is there a way to get a single TRUE or FALSE statement from comparing two vectors? For example, c(1,2,3) == c(1,2,3) produces TRUE TRUE TRUE where I would like it to produce only TRUE for use in an if statement. Likewise, when two vectors are not exactly identical (in all elements) I would like a single FALSE result, as opposed to c(1,2,3) == c(1,2,5) TRUE TRUE FALSE Any ideas?

I am trying to do a tutorial improvement on the wiki but I am having some problems with the auto formatting. Using httdp.conf produces http://httpd.conf when filtered. Using *.so produces .so and bold text there after. Is there any shorthand for the user for making text appear as it should without the linking and re-writes? Or does the admin have to change the filters in Instiki? Tesla

Hello, I'm running a very long for loop that usually takes hours. For my own piece of mind, it would be nice if I could check periodically and see which iteration the loop is on. A line of code that told R to print the iteration number every 100 or 200 iterations would be perfect. Does anyone know something like this? I've never known how to print anything within a for loop before the

Hi, Rsync is still hanging under cygwin for me. I'm using rsync 2.6.0 and i've tried cygwin-1.5.6-1 as well as a snapshot of 1.5.7. I've noticed that some people are having success. I shouldn't have to do anything interesting in order to make this work, right? *********************************************************************** This message is intended only for the use of

Hello, I'd like to plot an empirical cumulative distribution function, except instead of the fraction of values < x, I'd like the fraction of values > x. I think this can be done using the ecdf function in {Hmisc}. I installed the package and loaded it. However, when following the example given in the documentation, I get an error: x <- rnorm(100) ecdf(x,what='1-F')

Hello, I created an array to hold the results of a series of simulations I'm running: d.eta <- array(0,dim=c(3,3,200)) <simulation goes here and populates the array but it's not important> Then I tried to save the results using this: save(d.eta,file="D:/Simulation Results/sim 9-23-11 deta") When I later tried to reload them using this: d.eta <-

Hello, I have a longitudinal dataset where each individual has a different number of entries. Thus, it is of the following structure: x <- runif(12) id.var <- factor(c(rep("D1",4),rep("D2",2),rep("D3",3),rep("D4",3))) dat <- as.data.frame(x) dat$id.var <- id.var dat > dat x id.var 1 0.9611269 D1 2 0.6738606 D1 3

Hi, I would like to estimate a VAR of the form: Ay_t = By_t-1 + Cy_t-2 + ... + Dx_t + e_t Where A is a non-diagonal matrix of coefficients, B and C are matricies of coefficients and D is a matrix of coefficients for the exogenous variables. I don't think the package {vars} can do this because I want to include contemporaneous cross-variable impacts. So I want y1_t to affect y2_t and I

I want to use ActiveRecord outside of Rails to do processing on large tables. I want to be able to process the rows as they are retrieved rather than having to store the results in an intermediate array. Any suggestions? Looks like I could hack the adapter to provide an accessor to the underlying DBI handle. Anything cleaner than that?

Dear list member, John Fox proposed to me posting this problem to R-Help: I have written a function suited for Rcmdr and included this in a R-file located in Rcmdr/etc as well as an augmented `Rcmdr-menus.txt'. Now, I am faced with the following problem: method show() of a S4-class object works flawlessly, that is `doItAndPrint' works flawlessly and its output is returned correctly into

Is there a way to use the "link_to" function in a controller?

Is there a way I can have print statements in Rails code that will go either to the WEBrick console (prefered) or to a log file?

Hello, I'm clearly confused about the merge function. In the following r <- merge(x,y,all.x=T,all.y=F) my y vector has only unique values (no duplicates). So I don't understand how this can ever generate an r which is of greater length than x. I thought the default behavior was only matching rows are included, but that using all.x=T included rows with unmatched x's as well. If

I have a Model whose table name and primary key don''t follow Rails conventions. So I have used set_table_name() and set_primary_key() and can do the Record.find() method ok. My problem is that the Record.new(params[:id]) idiom in a controller complains: undefined method `stringify_keys!'' for "REAL_PKEY":String Is there something else I need to do?
