Using relaimpo or relimp with PLM and GLS
Dears,
Unfortunatelly, the packages relaimpo and relimp do not seem to work with
plm function (plm package) or gls function (in nlm package). I've been
studying on how to adapt one of them for this pourpose. In that sense, I
have two questions regarding to this work:
1) have anyone hard of any workaround for those incompatibilities, or at
least of any ideas on that - especially for plm?
2)

Longitudinal RelaImpo in LME4
I am currently using the relaimpo package to estimate the relative
importance of regressors (N= 4000):
> m1 <- lm(y ~ x1+x2+x3+x4+x5+, data=data)
> calc.relimp(m1, rela=TRUE)
> m2=boot.relimp(m1, boot = 500, rela=TRUE, type="lmg")
> booteval.relimp(m2)
> plot(booteval.relimp(m2))
In a new dataset with 3 measurement points (0,6,12 weeks), I want to

relaimpo - dummy variable
Hi,
I have a question related to the function "boot.relimp" (package relaimpo).
I have a model with numerical predictors and one dummy (class) variable. I
would like to calculate the relative importance of the predictors but I have
some problems with the dummy variable.
The name of the linear model is "lmbroadst.lc" and the dummy variable is
"datacon.landcover_gb"

Using a covariance matrix as input to relaimpo package
I'm having trouble getting the relaimpo package to use a covariance matrix as
input. I'm getting an error message that reads as follows:
Error in eval(m$weights, data, parent.frame()) :
numeric 'envir' arg not of length one
I'm guessing there is something wrong with the structure of my covariance
matrix, but it looks fine to me. Pardon my R ignorance if this is an easy

Bug in str or issue with class management in my package?
Dear developeRs,
with R 2.4.1 (and also 2.4.0), the function str() fails on objects of class
relimplmbooteval, if there are unused slots, which is very often the case. I
am not sure whether this is a bug in str() or a correct behavior of str()
that unmasks some sloppiness in my usage of S4 classes (that I am not aware
of)?
Reproducible example (package relaimpo needed):

Dear All:
I am calculating the relative importance of a regressor in a linear model.
Does anyone know how I can obtain/install the 'pmvd' computation type? I am
a US user.

relative importance of predictors
Hei Group,
I want to compare the relative importance of predictors in a multiple
linear regression y~a+bx1+cx2...
However, bptest indicates heteroskedasticity of my model. I therefore
perform a robust regression (rlm), in combination with bootstrapping (as
outlined in J. Fox, Bootstrapping Regression Models).
Now I want to compare the relative importance of my predictors. Can I rely

relimp
I am trying to use Rcmdr 1.5_4 with R-2.11.1 (order to run to run the new version of misdist-0.5.3 which is built under R-2.11.1). however relimp is required for Rcmdr and the version of relimp_1.0.1 downloaded from CRAN will not work with the latest version of Rcmdr (I get error message telling me to reload it). Is there any way round this problem or will there be a new version relimp that is

relaimpo
Hello,
Does anyone know if relaimpo only applies to "pure" multiple linear
regression models, i.e.
- linear in the variables AND linear in the coefficients
or is it safe to use it in models that are:
- non-linear in the variables BUT linear in the coefficients?
Thanks

package relimp
Hi,
i'm newbie for this, but it's very interesting, but how i have to
interpret the results
if i get i.e. this results ?
Is it correct -
if the "Ratio of effect sd" is positiv than the Numerator effects are
bigger , and the negative case vice-versa ?
Ratio of effect standard deviations: 0.954
Log(sd ratio): -0.047 (se 0.828)

R CMD check problem on R 2.6.1 RC
Dear R-developers,
I'm experiencing a problem with having an example run under R 2.6.1 RC
(downloaded and installed today, r43513), which does not occur on R 2.6.0:
The new version of package relaimpo does list package survey under
"Depends", and an example directly (i.e. not only from within a function of
relaimpo) uses function svydesign from package survey. Package survey is

strange crashes caused by 'cairoDevice' and 'tcltk' dialogues
Dear developers
I get some strange crashes when 'cairoDevice' and 'tcltk' are both
loaded in the same R vanilla session.
When executing the following in that order

I get a crash with the following message (see R-relimp-cairoDevice.txt):
The program 'R' received an X Window System error.

Please see the Rprofile file which i have modified as follows and after
that when I start R then I see that R says to me "TRUE" for all the

But when i try to use commands as simple as help("lm"), it doesnt work nor
any of the menu "Packages" is not working.

Extract a predictors form constparty object (CHAID output) in R
I have a large dataset (questionnaire results) of mostly categorical
variables. I have tested for dependency between the variables using
chi-square test. There are an incomprehensible number of dependencies.
I used the chaid() function in the CHAID package to detect
interactions and separate out (what I hope to be) the underlying
structure of these dependencies for each variable. What typically

no visible binding for global variable
Everyone,
I know that this has been discussed a few times on the list, but I
think that there is a high false positive rate of messages from

Here are two examples of from the caret package:
