About Passing Arguments to Function
Hi,
Below I have a function mlogl_k,
later it's called with "nlm" .
__BEGIN__
vsamples<- c(14.7, 18.8, 14, 15.9, 9.7, 12.8)
mlogl_k <- function( k_func, x_func, theta_func, samp) {
tot_mll <- 0
for (comp in 1:k_func) {
curr_mll <- (- sum(dgamma(samp, shape = x_func,
scale=theta_func, log = TRUE)))
tot_mll <- tot_mll + curr_mll

eliminate a partial argument match warning in R CMD check
Hello,
I'm seeing a nuisance warning when I run `R CMD check --as-cran
whatever_x.y.z.tar.gz`.
I generally work with these options set:
options(
warnPartialMatchArgs = TRUE,
warnPartialMatchAttr = TRUE,
warnPartialMatchDollar = TRUE
)
And I see this:

vectorized sub, gsub, grep, etc.
R pattern-matching and replacement functions are
vectorized: they can operate on vectors of targets.
However, they can only use one pattern and replacement.
Here is code to apply a different pattern and replacement
for every target. My question: can it be done better?
sub2 <- function(pattern, replacement, x) {
len <- length(x)
if (length(pattern) == 1)

[PATCH 0/4] Replace some uses of the Str module with PCRE.
Str is a pretty ugly regexp module. Let's try to replace it with
PCRE. This series of commits goes some small way towards that
eventual goal.
- - -
I wonder if there was a deep reason why we had this?
let unix2dos s =
String.concat "\r\n" (Str.split_delim (Str.regexp_string "\n") s)
I replaced it with what I think should be (nearly) equivalent:

Routes
hi all,
I want to move some routing tasks out of the router and into the
controller. The goal is to make Merb feel less like mod_rewrite and
give the user more control at the controller. The new Router is
simple: it takes the path_info (not the whole request) then outputs a
controller class and some parameters from the path matching. The rest
of the routing would be done at the controller level.

[PATCH v3 00/22] Replace almost all uses of the Str module with PCRE.
v1:
https://www.redhat.com/archives/libguestfs/2017-September/msg00135.html
v2:
https://www.redhat.com/archives/libguestfs/2017-September/msg00158.html
v3 is almost identical to v2, but I have added 4 extra commits to
almost finish the job of replacing Str everywhere possible (note it's
not possible to replace Str in common/mlstdutils or the generator
because those are pure OCaml).

cbind function
Hello everyone,
I would like to use the "cbind" function to construct a dataset, combining
some variable I defined before.
The codes are something like
var1 <- ...
var2 <- ...
var2 <- ...
...
data <- cbind(var1,var2,var3...)
The problem is I would like some flexibity in the data, i.e. the number of
the variables are not fixed. Is there a method of combine the uncertain
