I can't test it right now, but is this ok ?t.test.new <- function(x, y = NULL, alternative = c("two.sided", "less", "greater"), mu = 0, paired = TRUE, var.equal = FALSE, conf.level = 0.95, ...) { t.test(x, y, alternative, mu, paired, var.equal, conf.level, ...) }
You should name the arguments in the t.test call for safety. But just t.test.new <- function(..., paired = TRUE) t.test(..., paired=paired) is all you need, and for example allows formulae to be used.
2008/9/2 Prabhanjan Tattar <[EMAIL PROTECTED]>Hi R! I attempt to clear my question through this example. We know that the default functions for "t.test" is t.test(x, y = NULL, alternative = c("two.sided", "less", "greater"), mu = 0, paired = FALSE, var.equal = FALSE, conf.level = 0.95, ...) Suppose, I want to create a new function where "paired=TRUE". What is the simpler way of creating such functions? I did try, but without much success. Thanks in advance -- Prabhanjan N.
