It is impolite to put such a minor code fragment on a transient website. Also,

Thank you very much for your reply. I guess my question is whether it is

The the column name must be quoted in the index:

First, type
names(msub)
and then type
cn
and compare the output.
Probably, you will find a name in cn that is not among the names of msub.
To maybe make it easier to see the missing column(s), you can type
setdiff(cn, names(msub))
The expression
msub[,cn]
is intended to select columns

Dear R-helpers,
I would like to know if it is possible using R (earth packages or another one)
to realize robust MARS regression RMARS or RCMARS (C mean "conic").
Some authors have done it using MOSEK combined with Salford-MARS and special
MATLAB programs.

Hi Martin and list:

No matter how expert you are at writing regular expressions,
it is important to list which sorts of strings you want matched

When I run your code it appears that the c column is correctly transformed to
square roots, but the show() function is incorrectly indicating a log transform:

Try installing plyr, arm, scales and mi separately. If you get an

Dear Andreas,
As has been suggested, you're probably better off using an up-to-date version
of R and corresponding up-to-date packages, but if the only issue is that sem
can't be installed, the Rcmdr package should still work. The menu item for
confirmatory factor analysis will be missing, and

An old version of R would be fine if that was all you wanted, but no, you want
