Re: [R] is.na with lists....

People often use sum() to count how many boolean values are true, not length).

It's supposed to match the length. Perhaps you meant to use which(is.na())?

[R] is.na with lists....

[akshay kulkarni]

Dear memebers,
I have list of stock data OHLCData for 500 stocks, 
15 of whom are NA's. The following is the code:

require(quantmod)
getOHLCData <- function(NSESym) {
  OHLCData1 <- list()
  for(i in 1:500){
OHLCData1[[i]] <- tryCatch(getSymbols(NSESym[i], auto.assign=FALSE),
  error = function (e) {print(i); return(NA)})

  }
  return(OHLCData1)
}

 OHLCData <- getOHLCData(NSESym)

however, when I check for is.na, I get the following:

length(OHLCData)
[1] 500
> length(is.na(OHLCData))
[1] 500

length(is.na(OHLCData)) should return 15. Whats going wrong? I assume is.na 
returns TRUE if there is an NA.

Yours sincerely,
AKSHAY M KULKARNI

Dear Respected Sir,
Thank you for the quick response. However, the link your shared provides
the old version of wmtsa that is not working in R 4.2.0.
Can you please tell me any other solution for this issue?


Your response suggests that you do not understand how one installs a source 
package for R. You probably need to educate yourself about how to compile 
packages from source. Since the process is different for Linux, MacOS, and 
Windows, you would need to pay attention to the specific requirements of your 
unnamed OS.



BUT you do not need to compile the entire package to use a function in 
it:  You only need to source that particular function ... and any others 
it calls that you don't already have ;-)  That simplifies the task 
greatly.  With luck, Muhammad Zubair Chishti can source only the desired 
functions, and they will run and do what is desired with no further 
effort.  If not, Muhammad can be guided by the error message(s):  If 
they complain that a certain function is not available, Muhammad can 
find it and source it.  If the problem is more subtle, Muhammad can use 
"debug", as I earlier suggested.  Spencer Graves




You might find as I did that the wmtsa package has some dependencies that are 
also archived, namely pkg:splus2R (provided generously by Insightful for many 
years but apparently no longer) and pkg:ifultools. They both have 
incompatibilities that prevent compilation from source with my Mac setup. I did 
find a mirror that has a binary version of splus2R that did install and load.

install.packages("splus2R", repo="https://mirrors.vcea.wsu.edu/r-cran/;, 
type="binary", dependencies=TRUE)

So maybe part of your PhD training should be learning how to compile packages 
and address changes in the compilers being used as R evolves. That is beyond my 
capabilities for offering assistance. Alternately you might find a forum or a 
consultant with similar interests to yours. Again, I can offer no assistance 
because I have never used pkg:wmtsa and don't know what it provided when it was 
compatible with the CRAN universe.

Would package versions help? It would allow you to install a specific version 
of wmtsa into R 4.2.

Dear Respected Professor,
You are right. However, a student like me who doesn't know much R requires

Re: [R] A humble request

[Spencer Graves]

  Are you familiar with the "debug" function?


	  You can download the package, source the function you want to use. 
If it doesn't run or doesn't seem to give a sensible answer, debug(fun) 
followed by fun(arg1, arg2, arg3) will start the function then stop and 
invite you to walk through the function line by line.  You can look at 
what it does, and change it as you like.  Doing so should help you learn 
R while also making it easier for you to figure out how to make the 
function do what you want.



  Hope this helps.
