Hi, I need help to perform a Shapiro.test on a data frame, I know that
this test works only with vector but I guess there most be a way to
permor it on a data frame instead of vactor by vector (i.e. I've got 40
variables to analyze and its kinda annoying to do it one by one)
Thanks to anyone that can help me.

Try this: x <- data.frame(A = runif(10), B = rnorm(10)) lapply(x, shapiro.test) On Mon, Jun 22, 2009 at 3:15 PM, Gonzalo Quiroga <quirogagonzalo@gmail.com>wrote:> Hi, I need help to perform a Shapiro.test on a data frame, I know that > this test works only with vector but I guess there most be a way to > permor it on a data frame instead of vactor by vector (i.e. I've got 40 > variables to analyze and its kinda annoying to do it one by one) > > Thanks to anyone that can help me. > > Gonzalo Quiroga > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >-- Henrique Dallazuanna Curitiba-Paraná-Brasil 25° 25' 40" S 49° 16' 22" O [[alternative HTML version deleted]]
