R: “make” not found when installing a R-package fr

Question

The R Package ConvCalendar is not on Cran repository anymore (see here). However, because I have intensively used this package for previous projects, it would be nice to have it installed on my machine, even an older version would suffice.

(Windows 10 environment)

In the link above it is possible to download older versions of ConvCalendar from the archive. I thus did it, and tried installing it by running (having devtools also installed and loaded):

install.packages("ConvCalendar_1.2.tar.gz", repos=NULL, type="source")

However, I get the following error message:

> install.packages("ConvCalendar_1.0.tar.gz", repos=NULL, type="source")
Installing package into ‘C:/Users/myname/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)
* installing *source* package 'ConvCalendar' ...
** libs

*** arch - i386
Warning in system(cmd) : 'make' not found
ERROR: compilation failed for package 'ConvCalendar'
* removing 'C:/Users/myname/Documents/R/win-library/3.5/ConvCalendar'
In R CMD INSTALL
Warning in install.packages :
  installation of package ‘ConvCalendar_1.2.tar.gz’ had non-zero exit status

Looking for a solution to this problem.

Answer 1

what do you need is to update the Rtool, here is the link I had the same issue before once you update it will work.
