Prezactly.
Otherwise I don't see the differnce in applying the operation to a
totally numeric data.frame and a matrix.
The key line is
prep <- .checkinput(match.call(), parent.frame())
Among other things the model matrix is built in .checkinput( ) which is not
exported from the package namespace. So you have to get rough with it and use
penalized:::.checkinput

I am looking to build simple GUIs based on the R codes I have. The main
objective is to hide the scary R codes from non-programming people and make
it easier for them to try out different inputs.
For example,
1. The GUI will have means to upload a csv file which will be read by the R
code.
2.
Thanks a lot!
It worked perfectly
I just tried a simple modification...

I am using R for volatility calibration (Variance Gamma distribution).
My question is very basic and not at all related to mathematics!
y=spline(KK,CallPrices,,"fmm",,,strikes)
When calling spline function it returns a list y
The list contains some numbers which I have to subtract from ano
Hi,
I encounter similar problems as well and posted a while ago about this.
Namespaces are cool, but isn't it very much up to a package's position
in the search path (which is quite arbitrary depending on the packages
loaded) that determines which namespace "dominates"? That leaves it to
the u
hi thomas
thanks for your reply.
in the documentation of svytable, the argument na.rm=T is mentioned.
however, last night i figured out what went wrong in my tabulation: i had a
dataset which i attached and then defined the missing values - of course they
were not stored in the data set.

When I really need a png, I usually produce a pd
My understanding (which is pretty shaky when it comes to namespaces) is
that if you have things set up correctly then namespaces will make sure
that function calls within functions in the given package will be to be to
functions in that package and not to their doppelgangers in other packages

Dear expeRts,
I'm struggling a bit with arrays of lists. The nice thing about arrays is that
one can easily access subsets. For example:
arr. <- array(1:24, dim=c(2,3,4), dimnames=list(a=c("a1","a2"),
b=c("b1","b2","b3"),
c=c("c1","c2","c3","c4")))
arr.[,,4]
