Dear Samsad, The usual use of the arcsine transformation for proportions is arcsine-squareroot. Thus, in R, for proportions in p, you can use asin(sqrt(p)).
You could have found the asin() function yourself in several ways, including help.search("arcsin"), which turns up the help page for trigonometric functions. As well, the logit transformation, log(p/(1 - p)), is usually preferred to the arcsine-squareroot transformation for proportions because the former is unbounded. I hope this helps, John ----------------------------- John Fox, Professor McMaster University Hamilton, Ontario Canada L8S 4M4 Web: socserv.mcmaster.ca/jfox > -----Original Message----- > From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of Samsad Afrin > Himi > Sent: July 31, 2016 4:55 AM > To: r-help@r-project.org > Subject: [R] Arcsine Tranformation. > > Dear R-Team, > > How can I do arcsine tzransformation in R?
