Hi All, I am using DNAcopy package in R for copy number analysis of 500K chip. The final output which I get from DNA copy is too big to be printed in a file. So I am getting an error as "reached getOption("max.print") -- omitted 475569 rows " Can somebody please provide me the pointers with how to increase the limit for max.print . Thanks, Pooja DISCLAIMER\

Hello, I'm an MD working in an eye clinic. I'm learning by myself to use R for use in my research works and for implementation in a software project.

convert_mail = mbox:%h/mail Convert plugin. If set, specifies the source storage path which is converted to destination storage (mail_location) when the user logs in. The existing mail directory is renamed to <dir>-converted. I'm not entirely clear on what this does. If someone can clarify for me, I'll update the Wiki. I'm hoping it'll allow me to convert

Hi, I am wondering how to draw biplot with the same scales on both plots? For example, if the two plots have much different scales, generally the two x-y's are scaled so that the two plots are sitting in the center automatically. How to disable this?

Hi, R users: I want to fit my data into a normal distribution by using the command "fitdistr" in "MASS". I changed my data class from "ts" to "numeric" by >class(mydata)="numeric" but after using "fitdistr", I got the result below >fitdistr(mydata,"normal") mean sd NA NA (NA) (NA) the help doc of

In the ouput below, what is the "S" statistic (S = 96) that is used for Spearman? I don't have easy access to the books cited on the help page. Other texts and web sources that I have found use t or z as a test for Spearman, perhaps inappropriately. Can anyone tell me how S is computed or refer to a web resource? I see from the code for that: q <- as.integer((n^3 - n) * (1
