add zero in front of numbers
Dear R users,
I need to add 0 in front of a series of numbers, e.g. 1->001, 19->019,
Is there a fast way of doing that?

R string help
Dear R guru:
If I got a variable
aaa<- "up.6.11(16)"
how can I extract 16 out of the bracket?
I could use substr, e.g.
substr(aaa, start=1, stop=2)
[1] "up"
But it needs start and stop, what if my start or stop is not fixed, I
just want the number inside the bracket, how can I achieve this?
Many thanks

function for grouping
Dear All,
I'm wondering if there is a R function could give me all the
combinations of the grouping/cluster result, given the number of the groups.
e.g.
3 objects: x1 x2 x3, number of groups is 2
so the result will be
group1:x1,x2; group2: x3
group1: x1;group2: x2,x3
group1: x1,x3;group2: x2
many thanks

order(x,y, decreasing = c(FALSE, TRUE)) - how / elegantly?
I've found the need to compute a version of order(x,y)
where I want the sort order
for *increasing* x and *decresing* y ...
something we could imagine could be provided in the future as
order(x,y, decreasing = c(FALSE, TRUE))
i.e., using a 'vectorized' decreasing argument.
{No, I'm not volunteering right now!}
I've found the following R-level solution and

axis name editing
Dear All,
I'm generating a heatmap, is there a way to make Y axis name display
horizontally, X axis name display vertically?
I tried using "horiz=TRUE":
axis(1,at=1:dim(cor.meta.m)[1],labels=gsub("module","",pw.names),horiz=T
RUE)
but got warning message and the name is not displayed as I wish:
Warning message:

using glmnet for the dataset with numerical and categorical
Dear R users,
if all my numerical variables in my datasets having the same units, may I
leave them unnormalized, just do cv.glmnet
directly(cv.glmnet(data,standardize=FALSE))?
i know normally if there is a mixture of numerical and categorical , one has
to standardize the numerical part before applying cv.glmnet with
standardize=fase, but that's due to the different units in the numerical

Suppose I have a vector as
vect1 = as.character(c("ABC", "XYZ", "LMN", "DEF"))

[1] "ABC" "XYZ" "LMN" "DEF"
I want to reverse the order of this vector as
vect2 = c("DEF", "LMN", "XYZ", "ABC")
Kindly guide
