comment InstallR on OS X with external R installation on 10.0.1.0
@Leonid Shifrin. Many many thanks. The output of InstallR with 3.1.1 is InstallR::fail: Failed to install R. The following error was encountered: Unable to load dynamic libraries >>. The error mgs is different! I must be doing something wrong.

comment InstallR on OS X with external R installation on 10.0.1.0
@Leonid Shifrin - Many thanks for the reply. I am running R version 3.1. /Library/Frameworks/R.framework/Version shows that I have a dir called 3.1, 3.0 and Current. When I issue the command InstallR["RHomeLocation"->"/Library/Frameworks/R.framework/Resources","RVersion"‌​->"3.1"] the same error msg comes out. "RVersion" -> "R-3.1.0" sends the same msg too. Any thoughts?

comment InstallR on OS X with external R installation
If I have to start a new thread, please let me know. Everything works fine with 10.0.0.0, however after Mathematica was updated to 10.0.1.0, the R version that I use cannot be called anymore. InstallR["RHomeLocation" -> "/Library/Frameworks/R.framework/Resources"] Failed to detect the R version from the specified path to R home \ directory. Try using the "RVersion" option to specify the R version explicitly

comment On using DiracDelta[t] in OutputResposne in version 10. Different result from version 9
It seems that the bug was not fixed on 10.0.1.0 too.

Possible issues would do while bugs are not fixed!

comment On using DiracDelta[t] in OutputResposne in version 10. Different result from version 9
Does it mean that OutputReponse can only be used with DeltaDirac if one follows the trick shown above( fun = First@OutputResponse[sys, DiracDelta[t - 10^-27], t] // ComplexExpand // Simplify // Chop) ? Shouldn't a note be added to OutputResponse help on Mathematica?

@Nasser many thanks for placing the question. I have the same problem on my mac.

comment A simple ListPlot with different colours and a Tooltip
Many thanks. Adding Epilog as shown on the other does the job.

comment A simple ListPlot with different colours and a Tooltip
First of all, many thanks. Yes, it sounds like a static label. When I added PlotRange-> {{-0.5,1.5},{-0.5,1.5}} to see the labels, the size of the points have changed. Is that right? One final question - How can this solution be used inside Manipulate (y-values will change according to some rule) where only the plot is shown?

comment A simple ListPlot with different colours and a Tooltip
Yes. The first and the fourth have the same colour; the second and third point have the same colour but different from the previous set of points and finally the fifth point has a different colour when compared to the other two set of points.

comment Problems with RootLocusPlot
PlotPoints=7000 and MaxRecursion=15 (more than that, Mathematica sends a warning on my mac) are not enough to get rid of the distortion. The number of PlotPoints can be increased but the results take longer to show up. As for the distortion, it seems that increasing the Maxrecursion does the job. Many many thanks.

comment Problems with RootLocusPlot
Just a comment - if you change the limit of k from 0.99 to 0.99999, and from 1.01 to 1.00001, the entire real axis is covered by the loci.
