I used Colv=1:ncol(z), and i got the display the way i need it. Thanks. One more question, is there a way to increase the size of the color key in heatmap.2 so that all the tick values(for Eg.,in my case, values range between 10,000-50,000) can be seen clearly. In the normal case i am just able to see the initial tick value which is 10,000. Please suggest a better way to do this.
Thanks for the help. svakki. -----Original Message----- From: Sean Davis <[EMAIL PROTECTED]> To: "Akkineni,Vasundhara" <[EMAIL PROTECTED]>, r-help <[email protected]> Date: Wed, 22 Feb 2006 12:55:25 -0500 Subject: Re: [R] heatmap.2 in gplots package On 2/22/06 12:09 PM, "Akkineni,Vasundhara" <[EMAIL PROTECTED]> wrote: > Hello all, > > I am using the heatmap.2 function in the gplots package.
