I have a problem with installing packages. When I install it it gives me the warning package ‘xxm’ was built under R version 3.0.2 which I guess is not a problem. But later on I can access any data for example but none of the functions. For example the warring Error: could not find function “xxmModel” comes out. I do find the descriptions though in help. Any suggestions what went wrong?
Thank you for help in advance and it seem as the package I need so hopefully I will be able to do the multilevel SEM here.
