Hi! Yesterday I started to write my unit tests for the fist time using rails. I''m using this method: http://blog.codahale.com/2005/12/23/a-rails-howto-simplify-your-unit-tests/ My customer_test.rb looks like this: require File.dirname(__FILE__) + ''/../test_helper'' class CustomerTest < Test::Unit::TestCase fixtures :customers # Replace this with your real

I have so far used the following command glm(formula = s ~ age + gender + gemedu + gemhinc + es_gdppc + imf_pop + estbbo_m, family = binomial(link = "probit")) My question is 1. How do i discard the non significant selection variables (one out of the seven variables above is non-significant) and calculate the Inverse Mills Ratio of the significant variables 2. I need the inverse

Dear R users I have a data set which has five variables. One depenedent variable y, and 4 Independent variables (education-level, householdincome, countrygdp and countrygdpsquare). The first two are data corresponding to the individual and the next two coorespond to the country to which the individual belongs to. My data set does not make this distinction between individual level and country

hi, i am need to plot two or more sets of data in a 3d scatterplot, each set with different color. i tried Rcmdr, and the 3d scatterplot facility, based on rgl. that is what i need. but i cannot seem to code different sets of data differently. any help will be very helpful. i tried scatterplot3d, but it is difficult to get the right angle in it. i need to be able to rotate the axes, and

Hi, I am trying to plot densities given on a two dimensional grid. My data is in the an external file, and is arranged in three columns: x, y, density how may i get a plot of this? i would like to get (1) a three dimensional plot and (2) a color coded two dimensional plot. I have tried using image(x, y, density) but i am asked to put the data in ascending order. i am not sure how i may

I am typing the following on the command prompt: >variab = read.csv(file.choose(), header=T) >variab It lists 900,000 ( this is the total number of observations in "variab" ) minus 797124 observations and prompts the following message [ reached getOption("max.print") -- omitted 797124 entries ]] Is there a way to see the entire set of data, ie all of 900,000 obs, and

When we installed OpenSSH 2.1.1p4 on our Solaris systems, our users noticed that it did not honor password expiration consistently with other Solaris login services. The patch below is against OpenSSH 2.2.0p1 and adds support for PAM password changes on expiration via pam_chauthtok(). A brief summary of changes: auth-pam.c: * change declaration of pamh to "static pam_handle_t *pamh",

Hi, I need some suggestion on how I could modify the color on some rectangle that I have created using "image". In other words, I have a 5x5 matrix, say, m. m <- matrix(rnorm(25), nrow=5) I create a grid of rectangles by: image(m) Now I want to change the color of rectangle (3,3) to blue. I don't know how this could be done, and searching the web has

Hi, I am building an application where i need to have an admin interface from where the admin can assign permission for different methods (create, edit etc.) in controller based on roles . It should be similar to django administration, where we can assign permission on methods based on the role. How can i do the implementaton ? Can anybody give me some pointers on how to start ? Thanks and

Is there a way for a PAM module to force a client (and the server) to use kbd-interactive? As far as I can tell, when in the INITIAL_LOGIN phase, all communication with the client returns a PAM_CONV_ERR. I am trying to write a PAM module that will prompt a user for a second username and a second password in order for the module to succeed so that proper authentication relies on the ability

The auth-pam.c of sshd server contains a small flaw that allows empty password logins even if "PermitEmptyPasswords" option in the sshd config file is set to "no". The scenario is as follows: Using ssh the user tries to logon to the machine using an account that has empty password. If the user presses enter on the password prompt (NULL password) access is

Hi All, I am trying to use loess to smooth a 2D image, and also obtain the standard error for every pixel. I see that the standard error does not make sense. For example, running the following: library(stats) x <- array(c(1:100), dim=c(100,100)) y <- t(x) v <- exp(-((x-50)^2+(y-50)^2)/30^2) s <- v*0.02 g_noise <- rnorm(10000, mean = 0, sd = s) f <- v + g_noise f.loess <-

I have been unable to use any challenge/response based pam module (eg. pam_opie.so) for ssh authentication, because the challenge (needed to compute an appropriate response) is never shown during login. do_pam_conversation() in auth-pam.c will not print any prompts while in the INITIAL_LOGIN state, queueing them for later printing. Should users be able to override this (usually correct)

Hi I am using Stata 10 and I need to import a data set in stata 10 to R, I have saved the dataset in lower versions of Stata as well by using saveold command in Stata. My RAM is 4gb and the stata file is 600MB, I am getting an error message which says : "Error: cannot allocate vector of size 3.4 Mb In addition: There were 50 or more warnings (use warnings() to see the first 50)" Thus

Here is a patch that does TIS auth via PAM. It's controlled by a switch in the sshd_config. You'd use it by having a PAM module that sets PAM_PROMPT_ECHO_ON. eg, you could use it with pam_skey or pam_smxs. The patch is against the 2.9.9p2 distribution. I'm not on the list, a reply if this patch is accepted would be great. (But not required, I know some folks have a distaste for

Sir , I want to implement email section in ma web application.. so i found the method ''server_setting'' for it...

Hi, For some reason I have been unable to use the predict function when I desire the standard error to be calculated too. For example, when I try the following: l<- loess(d~x+y, span=span, se=TRUE) p<- predict(l, se=TRUE) I get the following error message: Error in vector("double", length) : vector size cannot be NA In addition: Warning message: In N * M1 : NAs produced by
