Re: [R] Changing a logical matrix into a numeric matrix

Nice solution :) Another one: m <- matrix(c(T,T,F,T),nr=2) m matrix(as.integer(m), dim(m)) - -- http://djhurio.wordpress.com/ http://twitter.com/djhurio http://www.linkedin.com/in/martinsliberts http://www.csb.gov.lv/ -- View this message in context: http://r.789695.n4.nabble.com/Chang

Hi, Try this, mode(m) <- "integer" HTH, baptiste On 10 January 2011 10:17, emj83 wrote: > > Hi, > > I would like to turn my TRUE/FALSE matrix into a 1/0 matrix (i.e. True=1 and > False=0) > >      [,1]  [,2]  [,3] > [1,]  TRUE FALSE FALSE > [2,]  TRUE  TRUE FALSE > [3,]  TRUE  TRUE  TRUE > >

Re: [R] Changing a logical matrix into a numeric matrix

Hi Emma, The easiest way I know uses a bit of a trick. If your matrix is named 'X' Then: X + 0 will convert it to numeric data. HTH, Josh On Jan 10, 2011, at 1:17, emj83 wrote: > > Hi, > > I would like to turn my TRUE/FALSE matrix into a 1/0 matrix (i.e. True=1 and > False=0) > > [,1

Re: [R] Changing a logical matrix into a numeric matrix

Just multiply by 1: > m <- matrix(c(T,T,F,T),nr=2) > m [,1] [,2] [1,] TRUE FALSE [2,] TRUE TRUE > m*1 [,1] [,2] [1,]10 [2,]11 -Oprindelig meddelelse- Fra: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] På vegne af emj83 Sendt: 10. janua
