quick and easy question regarding extracting multiple confidence intervals from logistic regressions

[Phil Wood]

Hi folks,

I'm trying to fix some old code in which I extract confidence intenrvals from multiple files in a directory. 

I had tried

modelResults <- extractModelParameters("mydirectory",recursive=TRUE)

based on the documentation at 
https://cran.r-project.org/web/packages/MplusAutomation/vignettes/Vignette.pdf

This generates the message, though:

extractModelParameters has been deprecated. Please use readModels("NameofMplusOutfileDirectory", what="parameters")$parameters to replicate the old functionality.

but when I try:

paramsnew <- readModels(" NameofMplusOutfileDirectory  ",recursive=TRUE, what="parameters$ci.stdyx.standardized")

or other permutations, I don't seem to recover them. I'm assuming the $parameters in the console message is some typo. 

Any hints, gang? TIA! Phil

Hi Phil,

I think you need something like

paramsnew <- readModels("NameofMplusOutfileDirectory",recursive=TRUE, what="parameters”)

Then, for each file, you should have:

paramsnew[[1]]$parameters$ci.stdyx.standardized

And you can assemble these with

lapply(paramsnew, function(x) { x$parameters$ci.stdyx.standardized })

Hope this helps!
