Hi! This is likely a problem with the underlying `lavCor` function in lavaan. How many observations do you have? 349 is a lot of variables for polychoric correlations...
Hi! Why would you want to constrain certain edges to zero exactly? If you have a large dataset you can also fit confirmatory models in the psychonetrics pacgage (see psychonetrics.org)...
Hi! Sorry for the late reply. I think this can be done easier if you just assign a dummy matrix for the penalizeMatrix argument: ``` # load packages packages
Hi Jens, I reproduce the error but this will take some time to figure out.. But you don't need to do step-up estimation. This also works: ``` library(CliquePercolation) library(psychonetrics) library(dplyr)...
Fixed in devel version; sorry for the delay!
Thanks! I am looking into this and indeed seems to be due to Hmisc, but I don't really get yet why it happens as qgraphd doesn't export any function from...
Hi Bill, Hm, qgraph doesn't import tidyr/dplyr. It imports ggplot2 but it seemed to me removing that from NAMESPACE didn't change the problem. I'll keep this issue open to look...
Thanks for the tips! This is not something I am actively developing, but maybe @GiulioCostantini who wrote this function can take a look.
This problem seems to be related to installing XML and OpenMx rather than semPlot. For some linux systems you can use `apt-get install r-cran-xml` for example.
Hi Yves, Thanks for the suggestions! I included these in `lavaan.R` now. Can you take a look? Best, Sacha
