The install.packages function in R is the automatic unzipping utility that gets and install packages in R. How do I find out what directory R has chosen to store packages? How can I change the directory in which R stores and accesses packages? Aug 15, 2008 Here the core.so binary has dependencies on a number of wx libraries. RPATH is set to look for libraries relative to the install location of core.so, and therefore the linker can find these libraries without needing to set LDLIBRARYPATH. You specify the value for RPATH at link time using the -R option. Linux is similar.

Set Run-Time Library Path on macOS Systems

At run time, tell the operating system where the API shared libraries reside by setting the environment variable DYLD_LIBRARY_PATH. Set the value to matlabroot/bin/maci64:matlabroot/sys/os/maci64.

The command you use depends on your shell. The command replaces the existing DYLD_LIBRARY_PATH value. If DYLD_LIBRARY_PATH is already defined, prepend the new value to the existing value.

If you have multiple versions of MATLAB^® installed on yoursystem, the version you use to build your engine applications mustbe the first listed in your system Path environmentvariable. Otherwise, MATLAB displays Can't start MATLABengine.

Set the path every time you run MATLAB. Alternatively, place the commands in a MATLAB startup script.

C Shell

Set the library path using the following command format.

For example, for MATLAB R2015a on a Mac system:

You can place these commands in a startup script, such as ~/.cshrc.

Bourne Shell

Set the library path using the following command format.

For example, for MATLAB R2015a on a Mac system:

You can place these commands in a startup script such as ~/.profile.

I need to add dev tools (such as JDK and friends) to my PATH. How do I change $PATH variable in OS X 10.8.x? Where does $PATH get set in OS X 10.8 Mountain Lion?
$PATH is nothing but an environment variable on Linux, OS X, Unix-like operating systems, and Microsoft Windows. You can specify a set of directories where executable programs are located using $PATH. The $PATH variable is specified as a list of directory names separated by colon (:) characters. To print the current settings, open the Terminal and then type:

OS X: Change your PATH environment variable

You can add path to any one of the following method:

$HOME/.bash_profile file using export syntax.
/etc/paths.d directory.

Method #1: `$HOME/.bash_profile` file

The syntax is as follows:

In this example, add /usr/local/sbin/modemZapp/ directory to $PATH variable. Edit the file $HOME/.bash_profile, enter:
vi $HOME/.bash_profile
OR
vi ~/.bash_profile
Append the following export command:

Save and close the file. To apply changes immedialty enter:
source $HOME/.bash_profile
OR
. $HOME/.bash_profile
Finally, verify your new path settings, enter:
echo $PATH
Sample outputs:

Method #2: `/etc/paths.d` directory

Apple recommends the path_helper tool to generate the PATH variable i.e. helper for constructing PATH environment variable. From the man page:

Nov 20, 2009 to get your serato crates, all you need to do is go into 'My documents' on your PC, then 'My Music', and in there you should see a 'Scratch Live' folder in there. Copy this folder to your external or Mac. Serato library mac. TIP: You can also import by dragging files and folders directly from Windows Explorer (PC) or Finder (Mac) into the Serato DJ Pro library. Loading a file to either deck from the files panel will automatically add it to your library. TIP: Dragging a folder into the crates view will instantly create a crate. This section will take you through the steps to move your library from your internal hard drive to an external hard drive for backing up: Ensure your Serato Software is closed. Connect your external hard drive to your computer. Open Windows Explorer (PC) or Finder (Mac) and navigate to your 'My Music' (PC) or 'Music' folder (Mac). About Serato Studio. Serato Studio is intuitive beat making software for DJs and producers. Spend less time hitting roadblocks and more time in the creative flow. DJ-friendly production. Make beats with your DJ hardware and get colored waveforms, DJ-style mixing chanel and your entire Serato DJ library. The Serato folder is located in the My Music folder on Windows and in the Music folder on Mac. Serato DJ Pro will also create a Serato folder on any external drive that you have added files from into the library. When you first exit Serato DJ Pro you will be prompted to backup your library.

The path_helper utility reads the contents of the files in the directories /etc/paths.d and /etc/manpaths.d and appends their contents to the PATH and MANPATH environment variables respectively.

(The MANPATH environment variable will not be modified unless it is already set in the environment.)

Files in these directories should contain one path element per line.

Prior to reading these directories, default PATH and MANPATH values are obtained from the files /etc/paths and /etc/manpaths respectively.

To list existing path, enter:
ls -l /etc/paths.d/
Sample outputs:

You can use the cat command to see path settings in 40-XQuartz:
cat /etc/paths.d/40-XQuartz
Sample outputs:

To set /usr/local/sbin/modemZapp to $PATH, enter:

OR use vi text editor as follows to create /etc/paths.d/zmodemapp file:
sudo vi /etc/paths.d/zmodemapp
and append the following text:
