Running R with browser without installing anything
Dear all, the company I work for has Matlab installed for
statistical/mathematical calculations and really not ready to go with R
(even installing exe file for R). Therefore I was wondering is it possible
to do analysis R using browser like IE, without installing anything?
Thanks for your suggestion.

Change Function based on ifelse() condtion
Below is my full implementation (tried to make it simple as for demonstration)
Lapply_me = function(X = X, FUN = FUN, Apply_MC = FALSE, ...) {
if (Apply_MC) {

} else {
if (any(names(list(...)) == 'mc.cores')) {

Need help on date calculation
Hi all, please see my code:

What is the correct way to find the number of months between "a" and "b",

Change Function based on ifelse() condtion
The reason that it works for Apply_MC=TRUE is that in that case you call
mclapply(X,FUN,...) and
the mclapply() function strips off the mc.cores argument from the "..."
list before calling FUN, so FUN is being called with zero arguments,
exactly as it is declared.
A quick workaround is to change the line
Lapply_me(as.list(1:4), function(xx) {
to
Lapply_me(as.list(1:4),

Change Function based on ifelse() condtion
My modified function looks below :

} else {
if (any(names(list(...)) == 'mc.cores')) {
myList = list(...)[!names(list(...)) %in% 'mc.cores']
}
return(lapply(X, FUN, myList))
}
}

Rolling window difference for zoo time series
Hi,
I have a 'zoo' time series as below :
Zoo_TS = zoo(5:1, as.Date(Sys.time())+0:4)
Now I want to calculate First order difference of order 1, rolling
window basis i.e.
(Zoo_TS[2] - Zoo_TS[1] ) / Zoo_TS[1]
(Zoo_TS[3] - Zoo_TS[2] ) / Zoo_TS[2]
.....
Is there any direct function available to achieve this?
Thanks,

Extracting numeric part from a string
Hi again,
I am struggling to extract the number part from below string :
"\"cm_ffm\":\"563.77\""
Basically, I need to extract 563.77 from above. The underlying number
can be a whole number, and there could be comma separator as well.
So far I tried below :

How to replace '$' sign?
Hello again,
I want to remove "$" sign and replace with nothing in my text.
Therefore I used following code:
> gsub("$|,", "", "$232,685.35436")
[1] "$232685.35436"
However I could not remove '$' sign.
Can somebody help me why is it so?

Change Function based on ifelse() condtion
That's fine. The issue is how you called Lapply_me(). What did you pass as
the argument to FUN?
And if you did not pass anything that how is FUN declared?
You have not shown that in your email.

Zoo rolling window with increasing window size
Hi Joshua, thanks for your prompt reply. However as I said, sum()
function I used here just for demonstrating the problem, I have other
custom function to implement, not necessarily sum()
I am looking for a generic solution for above problem.
Any better idea? Thanks,

A question on Programming
Dear all. Let say I have a group of codes which will be used in many places
in my overall R-code files. These group of codes will be used within a
for-loop (with a big length, like 10000 times) and also many other places
outside of that for loop. As this group of codes are being used in many
places, I thought to put them within a user-defined function.
Here my question is, is there any speed

How to look into the asterisked function?
Hi friends, there is methods() function to see the all available methods for
a particular function, for example:

"print.ar" "print.Arima"
In this list, there are some functions which are asterisked like

Code editor for writing R code
Bert,
Posit (formerly RStudio) has moved from RMarkdown to Quarto. They
still support RMarkdown but major new features will be in Quarto. For
new users a better choice would be Quarto.
See https://quarto.org/docs/faq/rmarkdown.html
Secondly, the OP stated he was using the VS-Code IDE, so there is no
reason to point him to the Posit/RStudio IDE for this functionality

Question on Round function
I happened to see these:
> round(.5, 0)
[1] 0
> round(1.5, 0)
[1] 2
> round(2.5, 0)
[1] 2
> round(3.5, 0)
[1] 4
> round(4.5, 0)
[1] 4
What is the rule here?
Should not round(.5, 0) = 1, round(2.5, 0) = 3 etc?

Change Function based on ifelse() condtion
Hi Christofer,
Before you made the change that I suggested, your program was stopping at
the statement: list(...) = list(..) .etc
This means that it never tried to execute the statement:
return(lapply(X,FUN,...))
Now that you have made the change, it gets past the first statement and
tries to execute the statement: return(lapply(X,FUN,...)).
That attempt is generating the error message because
