...an argument named "i" and I don't understand why. Could someone explain why the maxcor function definition needs to have this argument? maxcor = function(i, n = 10, m = 5) { mat = matrix(rnorm(n*m),n,m) corr = cor(mat) diag(corr) = NA max(corr,na.rm=TRUE) } > maxcors = sapply(1:1000, maxcor, n = 100) Thanks in advance.

Hi all, I have two basic questions, hope you should help me: 1. How do I save a log file in R with the results? For example, in Stata it can be done by using "log using c:\...\test.txt" 2. How do I display the execution time of one function like the one below: CalculaCorrelacao <- function(construto, n) { library(polycor) for (i in 2:n){ for (j in i:n+1){ x1

Hi, xl is currently ignoring the cpuid= variable in the config file. As I don''t like the current interface xm exposes (basically because it is complicated, unintuitive and very error prone), I implemented a new scheme for specifying CPUID flags policy, combining QEMU''s and Xen''s approach: cpuid = "<base>,<feature_name>=[01xks]*,... The patch includes a

Dear Professor Fox, Apologies for my oversight relating to the polychor command and thank you for your advice. I turned to the polychor command when trying to find an equivalent for the polychoric command found in the psych package (I am following a procedure outlined in Gadermann, Guhn & Zumbo, 2012 that uses this command rather than the polycor package) . The polychoric command is returning

Dear R users, I am a psychology postgraduate student who is relatively new to using R. I am currently developing a psychometric scale and have run into a few problems when using R to calculate a polychoric correlation matrix for my dataset. I am trying to produce a polychoric correlation matrix for calculating ordinal reliability estimates (eg. Alpha, omega).The set consists of 439 observations
