Hi all,
I have an array of lists. All lists have the same names and the vectors inside
each name have the same dimension.
For instance,
a[1:4]
[[1]]
[[1]]$var1
[1] 1 2 3 4 5
[[1]]$var2
[1] 6 7
[[2]]
[[2]]$var1
[1] 2 4 6 8 10
[[2]]$var2
[1] 12 14
[[3]]
[[3]]$var1
[1] 3 6 9 12 15

I use R-devel 3.2 in order to check "as cran" packages that I develop.
To maintain my package uptodate, I cannot use the update.packages()
directly because the packages are not still compiled for version 3.2.
Then I use:
update.packages(contriburl = contrib.url(repos=options("repos")$repos,

What you are asking is a bad idea on multiple levels. You will grossly
over-estimate the area under the ROC curve. Consider the 1-NN model: you
will have perfect predictions every time.
To do this, you will need to run train again and modify the index and
indexOut objects:
library(caret)

Hello,
I am using caret package in order to train a K-Nearest Neigbors algorithm. For
this, I am running this code:
Control <- trainControl(method="cv", summaryFunction=twoClassSummary,
classProb=T)
tGrid=data.frame(k=1:100)
trainingInfo <- train(Formula, data=trainData, method = "knn",tuneGr
You are separating the objects using commas, the correct should be semicolons.
Example:
xi1=matrix(data=rep(0.0,600),ncol=3);xi2=matrix(data=rep(0.0,600),ncol=3))
Best regards,

You can use 'factors' to assign labels to small integer values. E.g.,
> x <- c(1,2,3,4,3)
> fx <- factor(x, levels=1:5, labels=c("One","Two","Three","Four","Five"))
> table(fx)
fx
One Two Three Four Five

No, you are wrong. Read the docs! -- start with "An Introduction to R"
which ships with R.
Please do not post further until after you have done your homework.
x <- c(a=1,b=2,c=3)
See also ?names.

As I understand it right, there is no possibility to give variables or

Just for example. "x" need a name. And the four values (1, 2, 3, 4)

Dear all,
I want to convert to character arrays "2014-10:10 00:00:00" and
"2014-10-10:23:59:00" to an array of minutes :
2014-10:10 00:00:00
2014-10:10 00:01:00
2014-10:10 00:02:00
What is the best way to do it ?
thanks

I appreciate the feedback.
1) The paths are properly set...I only wonder if the spaces in the path to
wget.exe are problematic for R. The full path (C:\\Program Files
(x86)\\GnuWin32\\bin) is properly included in the return list for
Sys.getenv("PATH"). Sys.which("wget") returns:
>"C:\\PROGRA~2
I don't understand what you think it should actually return. As for why it
should behave the way it does now... hmmm, keep in mind that each
sub-expression needs to make sense as well.
Consider -integer(0)... applying the unary negation operator to a vector of
integers yields a new vector of
Tks, i have to do it.

Dear helpeRs,
let a <- 1:10
let b <- integer(0) first, then i will randomly write a integer differently
in the range(1,10) or NULL into b. for supposed 5 times.
then i want to get a[-b],that means i not want the values at index b.

Please do follow the posting guide and not sent HTML: it gets mangled.
There are two issues here:
1) Paths. Use Sys.which("wget") to see if the command is on your path.
I suspect it is not, and you need to set the path when running R in
the same way as is done for your shell. Compare the se
