search for: maxcor

Hello, While learning how to manipulate data with R, I found one example that I could not understand. In the following example, the function definition of "maxcor" has 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=TRU...

...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 <- construto[[i]] x2 <- construto[[j]] temp1 <- polychor(x1, x2, ML = FALSE,maxcor=.9999) corr[i-1,j-1] <- temp1 corr[j-1,i-1] <- temp1 } } return(corr) } Best regards, Raquel -- Raquel Rangel de Meireles Guimar?es Doutoranda em Demografia raquel at cedeplar.ufmg.br http://ufmg.academia.edu/RaquelGuimaraes Cedeplar - Centro de Dese...

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
