Hi all
I have problems in accessing a mer object called model.01 from a
workspace that was created with R 2.8.1 and saved with save into an
.RData file (on Windows XP or Ubuntu 8.10, don't remember anymore).
Now I want to open it in R 2.9.0 on Ubuntu 8.10. I use
# load workspace
load("name.RData")
which seems to work:
ls() # all objects in there
[1] "all" ? ? ? ? ?"all.dd" ? ? ? "model.01" ? ? "model.sorter"
It also recognizes the class of model.01:
[1] "mer"
attr(,"package")
[1] "lme4"
But when I want to print it or look at its structure:
print(model.01)
Error in slot(value, what) :
?no slot of name "Xst" for this object of class "mer"
Error in FUN(c("env", "nlmodel", "frame", "call", "flist", "X", "Xst", ?:
?no slot of name "Xst" for this object of class "mer"
Any idea what to do?
