R help - Oct 2015 - Problem with custom.model.names in plotreg (texreg)

Hi, I need some advice.

I'm using the package 'texreg' to extract effects in a multinomial
model.

While using the 'plotreg' command I've got a problem with the
subcommand
'custom.model.names'.
I'm able to have this subcommand working with the 'screenreg'
command.
However, when I use the subcommand 'custom.model.names' with the
'plotreg'
command, an error is what I get.

Is there any way to have the proper name of the models?
I do not like the, rather ugly, default naming ('Model 1', Model 2'
and so
on).


Thank you in advance,
Antonello Preti


Here some code for exemplification. It is a very elementary model with the
'iris' dataset.

### the data

data(iris)
dim(iris)
str(iris)


### Polytomous (multinomial) logit model

library(nnet)
mod.mn <- multinom(Species ~ Sepal.Length + Sepal.Width + Petal.Length +
Petal.Width , data = iris)

summary(mod.mn, cor=FALSE)


### coefficients

print(t(summary(mod.mn)$coefficients))

### standard errors

print(t(summary(mod.mn)$standard.errors))



#################################

library(texreg)

### custom.model.names OK

screenreg(mod.mn, custom.model.names = c("versicolor",
"virginica"))


### custom.model.names giving error

plotreg(mod.mn, custom.model.names = c("versicolor",
"virginica"))

### Error in plotreg(mod.mn, custom.model.names = c("versicolor",
"virginica")) :
###  The 'custom.model.names' argument must have the same length as the
'l'
argument.
