glmnet: obtain predictions using predict and also by extracting coefficients
All,
For my understanding, I wanted to see if I can get glmnet predictions
using both the predict function and also by multiplying coefficients
by the variable matrix. This is not worked out. Could anyone suggest
where I am going wrong?
I understand that I may not have the mean/intercept correct, but the
scaling is also off, which suggests a bigger mistake.
 Thanks for your help.

Error:non-numeric argument in my function
Hello!
I have a function:
zywnoscCalosc<- function( jedzenie, n1, n2, n3, n4, d1, d2, d3, d4 ) { 
ndf <- data.frame(nn1=n1,nn2=n2,nn3=n3,nn4=n4)
ddf <- data.frame(dd1=d1,dd2=d2,dd3=d3,dd4=d4)
for (i in 1:length(n1)){
wekt_n = ndf[i,]
wekt_n_ok = wekt_n[!is.na(wekt_n)]
dl_n = length(wekt_n_ok)
wynik = (1*wekt_n_ok)/(1*dl_n)
}
}
and I get an error like this:

What do you think about my function?
Hello,
I want to know what do you think about my function. I know that it isn't

better? (now is very slow and not ideal, sometimes I also get a mistake!)

Character coerced to factor and I cannot get it back
Something probably obivous but I don't see it.  I
needed to find the first 1 or two digits of some 5 and
6 digit numbers since they identified research sites
while the rest of the number was the plot id.  
I converted the numbers to characters, got the first 1
or  2 characters as appropriate and went to add the
new vector to the data.frame.  For some reason R is
insisting on turning the

lasso constraint
In the package lasso2, there is a Prostate Data. To find coefficients in the
prostate cancer example we could impose L1 constraint on the parameters. 
code is: 
data(Prostate) 
 p.mean <- apply(Prostate, 5,mean) 
 pros <- sweep(Prostate, 5, p.mean, "-") 
 p.std <- apply(pros, 5, var) 
 pros <- sweep(pros, 5, sqrt(p.std),"/")

Unexpected result of as.character() and unlist() applied to a data frame
Hi,

3 a 1
> unlist(dd)

Someone else might get something different. It all depends on the
values of its 'stringsAsFactors' option:

Using a 'for' loop : there should be a better way in R
I need to apply a yearly inflation factor to some
wages and supply some simple sums by work category.  I
have gone at it with a brute force "for" loop approach
 which seems okay as it is a small dataset.  It looks
a bit inelegant and given all the warnings in the
Intro to R, etc, about using loops I wondered  if
anyone could suggest something a bit simpler or more
efficent?

Three-dimensional (3D) movement using 'R'
Hi Everyone,
 
I have a question regarding the construction of 3D graphs in 'R', BUT
these graphs also need to illustrate movement (with time) of the
prostate gland (using radiological techniques).  I am not sure how to do
this in 'R' although I'm sure there is some way of doing it.

more efficient way to parallel
Dear All,
Suppose I have a program as below: Outside is a loop for simulation (with
random generated data), inside there are several sapply()'s (10~100) over
the data and something else, but these sapply's have to be sequential. And
each sapply do not involve very intensive calculation (a few seconds only).
So the outside loop takes minutes to finish one iteration.
I guess the better way

  I am now using  R and SAS to fit the piecewise linear functions, and what
