Hi Eric,Thanks for the explanation. Is there a way to save the results automatically after the analysis gets over?. As I recently lost the results, because I didn't save the results. I don't want to run the sink or save command after the analysis is over rather run the command for saving the file before starting to run the analysis, so the file gets saved automatically after the script has

Hi Eric,I tried as you suggested but I could not find the output in the text file I created (attr.txt) net <- loadNetwork("C://Users//Priya//Desktop//Attractor analysis_all genes//synaptogenesis//regulationof_dopamine_signaling_submodule3.txt")sink("C://Users//Priya//Desktop//Attractor analysis_all genes//synaptogenesis//attr.txt") sink() attr <- getAttractors(net,

Let's try a simple example. > # Create a script file of commands > # Note we must print the results of quantile explicitly > cat("x <- rnorm(50)\nprint(quantile(x))\nstem(x)\n", file="Test.R") > > # Test it by running it to the console > source("Test.R") 0% 25% 50% 75% 100% -2.4736219 -0.7915433

Some comments: 1. sink() does not return a value. There is on point to set attr <- sink(...). Just give the command sink("C://....etc") 2. to complete the saving to the file you must give a second sink command with no argument: sink() So your code would be (pseudo-code, not actual code) sink( "filename" ) do something that prints output which will be captured by sink

Hi Priya, You did not follow the logic of the pseudo-code. The sink("filename"), sink() pair captures whatever output is generated between the first sink statement and the second sink statement. You need (possibly) to do: sink("C://Users//Priya//Desktop//Attractor analysis_all genes//synaptogenesis//attr.txt") net <- loadNetwork("C://Users//Priya//Desktop//Attractor

I''m attempting to learn Ruby on Rails, but these errors aren''t helping. I''m currently trying to follow the lessons available on www.learningrails.com. I received this error after trying to visit a page generated by using the scaffold command. Actually, this is all I did up until the error: rails sample2 -d mysql mysqladmin -u root -p create sample2_development ruby

See my screenshot of the command here. http://a.imagehost.org/0843/mysqladmin.png When I type the following: mysqladmin create <database_name> --user=root --password=xxxxxxxx Is my command executed simply by pressing "Enter" after the command? Am I missing some syntax? If the command has been executed , what directory can I find this database? How does this relate to MySQL
