How to set PATH for R installed in my directory

Question

I would like to install “R” into my directory in the server,

Here is what I have tried following the guidance here: Install R in my own directory

wget http://cran.rstudio.com/src/base/R-3/R-3.2.2.tar.gz
tar xvf R-3.2.2.tar.gz
cd R-3.2.2
mkdir ~/Programme # create a folder called “Programme” for R
./configure --prefix=$HOME/Programme
make && make install

Then when I tried set the PATH for R:

    vi .bash_profile #create a .bash_profile 

#set PATH so it includes user's private bin if it exists  

    if [ -d "HOME/bin" ];then   
        PATH="$HOME/bin:$PATH"  
    fi  
    PATH="$PATH:$HOME/Programme/bin/"  

but when I use which R still I am using the R installed for the whole server, instead of the R in my directory. the problem is if I could not use my own R, then I could not install other R packages.

Could anyone solve this problem? Thanks very much.

I tried set the .bash_profile into this way:

#set PATH so it includes user's private bin if it exists 
if [ -d "$HOME/bin" ];then
    PATH="$HOME/bin:$PATH"
fi
PATH="$HOME/Programme/bin/:$PATH"

but still could not get it worked. the R in my directory can be executed:

[myusername@host ~]$ ~/Programme/bin/R

R version 3.2.2 (2015-08-14) -- "Fire Safety"

Answer 1

Thank you, everyone! You guys are right, I should put the my own R' path first.

And I am sorry that I made another mistake.

I was using C shell!

I realised that when I "source" the .bash_profile, I got

"if:Expression Syntax error"

I searched it, found: https://stackoverflow.com/questions/14440105/bashrc-if-expression-syntax-error someone indicated that:"'if: Expression Syntax' is not an error bash would give you. Perhaps your shell is not bash. " So I checked my shell :

"echo $0"

got:

"-csh #!!!"

Then I created .cshrc:

{setenv PATH $HOME/Programme/bin/:$PATH}

And then logout and login again. Problem solved!

R is in default $PATH, put you own first:

 PATH="$HOME/Programme/bin/:$PATH" 

(assumming $HOME is /user/institute/username )

• do not use PATH="$PATH:/user/institute/username/Programme/bin/:$PATH" this will still put /usr/bin before /user/institute/username/Programme/bin.

you set

if [ -d "HOME/bin" ];then   
    PATH="$HOME/bin:$PATH"  
fi

This might be usefull for any programs you have in $HOME/bin, but not for R.
