Thanks for your concern. However, I failed to install the file after downloading form the link that you provided. Here is the error message... install.packages("C:/Users/Arif/Downloads/DCchoice_0.0.15.tar (1).gz", repos = NULL)
Installing package into ‘C:/Users/Dr Arif/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)
Error in install.packages : type == "both" cannot be used with 'repos = NULL'
install.packages("C:/Users/Arif/Downloads/DCchoice_0.0.15 (4).zip", repos = NULL, type = "win.binary")
Installing package into ‘C:/Users/Arif/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)
Warning in install.packages :
cannot open compressed file 'DCchoice_0.0.15 (4)/DESCRIPTION', probable reason 'No such file or directory'
Error in install.packages : cannot open the connection
Please help for further procedure... TIA.
