Problem using run_IQRsysProject

[Nicolas Sundqvist]

Dear Henning and all,

I have a problem when using run_IQRsysProject. I get an error message that i don't understand.  I have the following setup

est1 <- as_IQRsysEst(sysobj1)
proj1 <- IQRsysProject(est1,
                                        "files/Example1_EGFR/Models/RUNSmodel1",
                                        opt.nfits = 3
)

optsys1 <- run_IQRsysProject(proj1,
                                                      FLAGgof = FALSE)

and I get the following error message 

I've looked but I don't really understand where I specify the "studyname" argument. Can anyone tell me what i might be doing wrong?

I have version 99.0.0 of IQRtools and versions 1.1.0 for the dMod and cOde packages.
