As a Dropbox user, I often need to start a web server from a non-standard root folder location. Under Windows, I have been using Mongoose and loves it. Mongoose is a single .exe file that can be put into the root folder of a web project.
For Mac and Linux with Python, life is even better. A light weight server is already installed. I just need to run the command
sudo python -mSimpleHTTPServer 80
and the web contents can be accessed through the URL
http://localhost
Although R and Matlab have many similarities, switching between the two languages is not always easy. Below is a lookup table that hopefully will make the process easier.
| Matlab | R | Note |
|---|---|---|
| size | dim | |
| find | which | |
| ( | [ | |
| s(offset:(offset+len-1)) | substr(s, offset, len) | |
| @x lambda(x) | function(x) { lambda(x) } | Anonymous function in Matlab cannot contain more than one statements. |
| num2str | as.character | |
| ischar | is.character | |
| class | class | |
| unique | unique | |
| & (|) | & (|) | element-wise logic operators |
| ~ | ! | |
| sum | sum | vector function |
| length | length | vector function |
| dec2hex | as.hexmode | |
| strcat | paste |
