 Q:

r modify and rebuild package

I'm trying to use the SemiMarkov package and I want to change one small line of code in there. I've done some digging via:
getAnywhere("semiMarkov")

& I've identified that I want to change this line:
hessian <- diag(ginv(hessian(V, solution)))

to try something like:
hessian <- diag(ginv(pracma::hessian(V, solution)))

How do I go about this? Do I need to rebuild the package from scratch, and if so do I need rTools etc for this, or is there a simple-ish workaround (I'm a relevant R novice)? I've done some searching online and can't find anything obvious. Any ideas/pointers gratefully appreciated.

A:

If you'd like to simply test out the effect of that change in an interactive R session, you can do so using trace(). Here's how:

Type trace("semiMarkov", edit=TRUE)
In the text editor that that launches, edit the line of interest.
Save the modified file.
Close the text editor
Back in R, use the modified function.

Linux environment
Starting with downloading the package source from CRAN.  

This is the landing page: https://cran.r-project.org/web/packages/SemiMarkov/index.html 
This is the package source: https://cran.r-project.org/src/contrib/SemiMarkov_1.4.2.tar.gz

Download and extract the source: 
wget https://cran.r-project.org/src/contrib/SemiMarkov_1.4.2.tar.gz
tar -xvzf SemiMarkov_1.4.2.tar.gz

This should result in a directory named SemiMarkov.  Open up the source (cd SemiMarkov), and modify as necessary.  
Next, build the changes: 
cd..
R CMD build SemiMarkov/

This will result in a new archive file named SemiMarkov_1.4.2.tar.gz. 
Lastly, install your modified archive:
R CMD INSTALL SemiMark

  Q: 

 r modify and rebuild package 

 I'm trying to practice the SemiMarkov software and I desire to change one small line of code in there. I've perform some digging via: 
 getAnywhere("semiMarkov ") 

 & I've identified that I desire to change this line: 
 hessian < - diag(ginv(hessian(V, solution) )) 

 to try something like: 
 hessian < - diag(ginv(pracma::hessian(V, solution) )) 

 How do I rifle about this? Do I need to rebuild the package from start, and if so do I need rTools etc for this, or is there a simple - ish workaround (I'm a relevant radius novice)? I've done some searching online and can't find anything obvious. Any ideas / arrow gratefully appreciated. 

 A: 

 If you'd wish to simply test out the consequence of that change in an synergistic R session, you can do so using touch (). Here's how: 

 Type trace("semiMarkov ", edit = TRUE) 
 In the text editor that that launches, edit the line of interest. 
 Save the modified file. 
 Close the text editor 
 Back in R, use the modified function. 

 A: 

 Linux environment 
 Starting with downloading the software beginning from CRAN.

 Download and excerpt the source: 
 wget https://cran.r-project.org/src/contrib/SemiMarkov_1.4.2.tar.gz 
 tar -xvzf SemiMarkov_1.4.2.tar.gz 

 This should leave in a directory named SemiMarkov.   unfold up the source (cd SemiMarkov), and modify as necessary.  
 Next, build up the changes:
