blavaan does not load

[christop...@gmail.com]

Various attempts to load blavaan are in vain:

Error: package or namespace load failed for ‘blavaan’ in .doLoadActions(where, attach):

 error in load action .__A__.1 for package blavaan: is(module, "character"): object 'm' not found 

Uninstalling then reinstalling did not help, restarting R or RStudio does not help. Is this a known problem?

Christopher,

I have not heard this one before. Could you send the results of your sessionInfo() and also clarify whether you are installing from CRAN or from github? If you haven't, you might also check that your other packages are updated.

Thanks,

Ed

Can your provide more information? Like your sessionInfo(), also this might be a problem with rstan instead of blavaan. Please thys syntax and see if you have a working stan

library(rstan)
scode <- "
parameters {
  real y[2];
}
model {
  y[1] ~ normal(0, 1);
  y[2] ~ double_exponential(0, 2);
}
"
fit1 <- stan(model_code = scode, iter = 1000)
print(fit1)

If this doesnt work it means the problem is with stan. Might be that you need to install the latest version of RTools

Thanks. Running the suggested code for rstan clarified that software was missing (updated XCode?). I'm working on it and will report back, whatever the outcome.

PS. Installed from CRAN: install.packages()

Thanks a lot! The suggested code resulted in the suggestion to download/install additional software. Done that, blavaan seems to run smoothly now.
