R | Rcmdr ; Rattle on R3.1 and Mac OSX yosemite

-
Today I tried to install Rcmdr on my MBP( yosemite ) and found that it was the installation was not successful and kept throwing a lot of errors and also some of the dependancies packages were not getting installed. I also noticed that some of the dependancies are not available for R.3.1 and yosemite. After spending a lot of time googling and trial and error, now I got everything working 

Steps to do
  1. Since Rcmdr uses xWindows system, we need a OSX version of the same. So make sure you have installed the Quartz(X11) from this site -http://xquartz.macosforge.org/landing/
  2. Install macports - https://www.macports.org/install.php
  3. Make sure you have already installed the Xcode. Since some of the dependancies binaries are not available for the current R version, we might have to compile them from source
  4. Download RGtk2 source and cairoDevice source from CRAN ( download the "packaged source")
  5. run the below code.(one by one)
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
sudo port selfupdate
sudo port install pkgconfig
export PATH=/opt/pkgconfig/bin:$PATH
sudo port install gtk2 +x11
export PKG_CONFIG_PATH=/opt/local/lib/pkgconfig
R CMD INSTALL [Rgtk2...gz file(downloaded in step4)]
R CMD INSTALL [cairodevice...gz file(downloaded in step4)]
Sys.setenv(PATH=paste0("/opt/pkgconfig/bin:",Sys.getenv("PATH")))
Sys.setenv(PKG_CONFIG_PATH="/opt/local/lib/pkgconfig")
install.packages("RGtk2", type="source")
install.packages("cairoDevice", type="source")
install.packages("rattle", type="source")

Rcmdr 

 Now go to R-Console (or R-studio) and type 
library(Rcmdr)
and you should see a window pop-up like below



Rattle
The rattle GUI gives access to a range of multivariate graphics, regression and classification routines.

library(rattle)
rattle()

the screen should look something like this

react-bootstrap-table | header column alignment fix

-

I am working with react-bootstrap-table. Its a great module with few teething problem. for example whenever I have a lots of columns (in the table) my header column is misaligned with the columns in the dataarea. example: (before the fix) after applying the fix ( note that now you have a scroll bar too) Reason for the problem: In react-bootstrap-table "header" is a table and the data is another table. Since they are 2 different tables sometimes the header column width gets misaligned from the column of data table. Fix-Logic applied: The idea is simple, First I allow the table to be rendered as it is  Then first adjust the width of the data table columns using the width of the respective header column width. But remember only for the columns whose width is lesser than the header respective column width.  Now get the width of all data-columns and set the same to the width of the respective header columns. and tadaaaa the table in perfect alignment now.
