Request: Increasing MAX_NUM_DLLS in Rdynload.c
This is a request to increase MAX_NUM_DLLS in Rdynload.c in from 100 to 500.
On line 131 of Rdynload.c, changing
#define MAX_NUM_DLLS 100
to
#define MAX_NUM_DLLS 500
In development of the mlr package, there have been several episodes in the
past where we have had to break up unit tests because of the "maximum
number of DLLs reached" error. This error has been an inconvenience that is
going to keep happening as the package continues to grow. Is there more
than meets the eye wit...

Request: Increasing MAX_NUM_DLLS in Rdynload.c
Thanks Henrik this is very helpful! I will try this out on our tests and
see if gcDLLs() has a positive effect.
mlr currently has tests broken down by learner type such as classification,
regression, forecasting, clustering, etc.. There are 83 classifiers alone
so even when loading and unloading across learner types we can still hit
the MAX_NUM_DLLS error, meaning we'll have to break them down further (or

Reference to use of MLR in industry and biology
I apologize in advance for posting a question not related to R.
I need references to papers that use multiple linear regression in an industrial application and also in a biological experiment.
This is aimed to biologists/chemists (non-statisticans) so if anyone has written a brilliant paper where the use of multiple regression is important and also understandable to people with little

Request for information
Dear Developers,
I am a data science student. I wish to implement Neuro fuzzy Classifier,
Adaboost, MLkNN Multi label algorithms for web document classification.
I could not find packages and steps for above mention algorithms in mlr
<https://mlr-org.github.io/mlr-tutorial/devel/html/multilabel/index.html>.
Hence i request you to give your valuable suggestions.
In need of your guidance,
Thanking you.

That dreaded floating point trap
Hi,
I had a piece of code which looped over a decimal vector like this:
for( i in where ){
thisdata <- subset(herde, herde$mlr >= i)
# do stuff with thisdata..
}
'where' is a vector like seq(-1, 1, by=0.1)
My problem was: 'nrow(thisdata)' in loop repetition 0.4 was different if
'where' was seq(-1, 1, by=0.1) than when 'where' was seq(-0.8, 1, by=0.1)
It went away after I changed the...

Multilingual Rails v0.6

My knowledge of Japanese and other asian languages is VERY limited.
If you Japanese guys think that the way
MLR integrates compose/decompose/normalize right now is wrong/
backwards, please tell me right now so I can
make a more natural-to-use implementation for the next version.

multi-regression with more than 50 independent variables
...ables, the results
are reasonable. With increasing the number of independent variables more
than 11, the coefficients will get ?NA? in the output. Is there any
limitation for the number of independent variables in multiple linear
regressions in R? I attached my dataset as well as R codes below:
mlr.data<- read.table("./multiple.txt",header=T)
mlr.output<- lm(formula = CaV ~ SHG + TrD+ CrH+ SPAD+ FlN+ FrN+ YT+
LA+ LDMP+ B+Cu+ Zn+ Mn + Fe+ K + P+ N +Clay30 +Silt30 +Sand30

Multinomial Logit Regression
Hi all,
I have a dataset with a response variable with three categories (1, 2, 3)
and a lot of continuous variables. I'd like to make a MLR with these
variables. I've been watching the libraries nnet and zelig for this purpose
but I don't understand them well.
I use a training sample data to make the MLR.
train.set <- sample(1:1000,1000*0.7)
I have done this:
library(nnet)
net <- nnet(response.variable~., data = train...

A modern object-oriented machine learning framework in R
...DictionaryLearner!
Pero obtuve el mismo error. Como muestro.
Reconozco el error de imprecisión al plantear la duda, por no poner esta
experiencia. Este resultado, por decirlo de alguna manera, me mueve a
pensar que el problema está en el reposititorio de la librería mlr3, al
buscar la técnica de clasificación.
No sé si hay algo más que no he hecho,
además de cargar las librerías que entiendo deben estar, es decir:

library(mlr3)

postResample R² and lm() R²
Hello,
I'm with a conceptual doubt regarding Rsquared of both lm() and
postResample(library caret).
I've got a multiple regression linear model (lets say mlr) with anR² value
of 67.52%.
Then I use this model pro make predictions with predict() function using the
same data as input , that is, use the generated model to predict the value
associated with data that I used as input.
Next, if I apply postResample() to the observed and predicted data, why do...

modelling a particular design
...) irrespective
of (i.e. controlled for) z at any of the measurements.
(1) What would be a good way of testing for the hypothesis in the context of
a GLM or a canonical regression analysis? I can see that in a parametric
testing and for a single measurement of y a simple multiple linear
regression (MLR) or an ANCOVA (or a RANCOVA in a nonparametric approach)
would do the trick. However, I am not sure how to tackle the issue facing
repeated and at least biologically somehow interdependent measurements and
the goal to include as much measurements as possible even though the sample
size differs. I t...
