I have downloaded the zip file required for installation and followed the instructions given on the site.
install_course_zip("C:\\Users\\Sanket\\Downloads\\swirl_courses-master.zip\\", multi=TRUE, which_course="Open Intro")
error message:Error in unzip(path, list = TRUE) : zip file 'C:\Users\Sanket\Downloads\swirl_courses-master.zip\' cannot be opened
We can install that cousera swirl package in two type
one is
install.packages("swirl")
another one is install by manually..
In rstudio right side some options are there like package, plot, file,help
there you need to go package>install>
there you need to choose package archive (install from )in first option package>install>install from> package archieve(*.zip, *.tz)
then you can navigate the your zip folder then click install
