Docstring unable to view the comment

[kartik1611]

I am unable to view the comments after changing the below function name and trying to view the comments , snippet and code below for reference purpose

Initially my function name was square but then changed to another variable and then tried to view the comments but I was unable to do so

### code for reference purpose
`
rm(list=ls(all=T))
library(docstring)
ab <- function(a){
#' @title :square function
#' @description : print the squares of the number
#'from 1 to the input given
#' @param : input number
#' @output : provide the squares of the input range
for(i in 1:a){
b <- i^2
print(b)
}
}
?ab

`

I could not replicate this issue. Are you still affected by it?

I'm also unable to reproduce this error. If you have any further info let me know but I'm going to close this for the time being.

I do have the same issue.

Interesting - I still can't reproduce but can you provide the output of sessionInfo() and Sys.info()? That might help with debugging.

[KristanRomano]

The above code is working now. But this one does not

library(docstring)
prova<-function(x){
#'@title prova
#'@description blabla
#'@param x blabla
#'@output x-1
x-1
}

I had a similar problem. I fixed it by using docstring(my_function) rather than ?my_function. I got an loadNamespace(x) error regarding rstudioapi the first time, but could solve it by

install.packages("rstudioapi")
library(rstudioapi)

I found that we can't have two functions that both have docstrings. They have the issue most likely because they had another function with docstrings.

library(docstring)
test1 <- function(x) {
  #' This is a test function
  #' @param x a number
  x <- x + 1
  return(x)
}

test2 <- function(x) {
  #' This is a test function
  #' @param x a number
  x <- x + 1
  return(x)
}

?test1
?test2

The output shows test1 is fine but not test2:

> ?test1

> ?test2
No documentation for ‘test2’ in specified packages and libraries:
you could try ‘??test2’

This is very helpful information. If you run docstring(my_function) once, you will be able to run ?my_function in the future.

Interesting. I'll investigate. Are you using RStudio? Does the problem persist if you use R outside of RStudio?

Yes, I use RStudio. I tried RGUI again, and got the same error.

It seems there has already been a pull request to fix it.
