Not possible in the current implementation. In principle it
would be possible to extend earth so the user-defined "allowed"

selection of hinge function with restrictions, machine learning, earth package,
Hi,
I have a few questions regarding machine learning packages in R, e.g.
earth package
and its forward pass and prunning pass, and hinge functions selection in the
example below.
1) How could I force the algorithm to generate knots in hinge function only
with values < 90 for e.g. variable doy?
2) Is it possible to restrict the algorithm to generate maximum number of
terms per a selected

Error in solve.default message using lme
Dear All,
I?m using lme to analyze a time series gene expression data. I don?t have
all animals in all times, the number of animals in each time is different
and I have lots of NA values.
An example file can be downloaded at lbmp.fcav.unesp.br/leonardo and the

Longman iBT 2.0 Toefl
Hello. Can anyone please take a second to help me out with this problem? I try to run Longman iBT 2.0 Toefl with the last version of Wine / Lubuntu / FGLRX (video driver for ATI HD 4330 ) / Java. I have the last version of all these... As you can see, the program runs but some items are not displayed or wrong displayed. Moving the pointer or moving the window can make the image better or worse.

[LLD/ELF] - Should we implement .note.gnu.property and/or Intel CET in LLD ?
Linux GABI [1] introduced new .note.gnu.property section which contains a program
property note which describes special handling requirements for linker and run-time loader.
LLD does not support .note.gnu.property yet.
GABI specifies 2 types of entries:
GNU_PROPERTY_STACK_SIZE and GNU_PROPERTY_NO_COPY_ON_PROTECTED:
* GNU_PROPERTY_STACK_SIZE: Its pr_data field contains an integer in the format

I think we should wait until there is someone wanting to use these features with lld.

Newly installed version; can't run lm function
New installation seems to have behavior I cannot figure out. Here is illustrative sequence where I load a small data set (test) from Crawley's files and try to run a simple linear model and get an error message. Oddly, R reports that the variable 'test$ozone' is numeric while, after attaching test, the variable ozone is not numeric. Can someone please help? This behavior is

Identifying objects from a data set
Hello
Given the following data for a data set called airquality. To identify the nature of the objects from the data set airquality example "Ozone" would it be best to use the command is. like is.character(airquality$Ozone) ....... I tried attributes(airquality$Ozone) but it came up null. Would there be a better way to identify these objects.
Thanking you in advance for your

need help with matrix manipulation
I hope my problem is not too basic to post here. I am a beginner having
problems with some matrix manipulation. The data I am working with are
sites with hourly ozone readings and is in a matrix where each row is a site
and each column is an hourly reading. So for 10 sites, one day's worth of
data is a 10x24 matrix - column 1 is the ozone measurement for midnight GMT,
column 2 is ozone at

ozone data
Hi just a quick inquiry
Sorry if this is too trivial but I am just a beginner in R.
I am looking at the plyr package and I am intrigued at how data(i.e. ozone, baseball) is loaded without having to type data(ozone). Are they automatically loaded when i call library(plyr)? I want to do the same thing when I make my package. How does one accomplish this?
Also, are there any beginner guides on how

k nearest neighbours
I want to
1) Select for each of the n points in a matrix A, those of the m points
in B that lay within a given radius.
2) Of those points within the radius, select the k nearest ones.
What I now do is
1) Create an n*m matrix C were I put the distances from all the points
in B to the points in A and make NA those cells were the distance is
larger than the radius. (The points are geographical

Lo del "get" de Marcelino me da la respuesta a lo que yo exactamente

fun.aggregate=mean in reshape
Hi all,
We are facing a problem while introducing ourselves to Reshape package
use. Melt seems to work fine, but cast fails when we use mean as
fun.aggregate. As you see here, length and sum work fine, but mean
throws this same error whatever dataset we use.

them). I get the following error:
