Re: [R] dimension-preserving matrix coersion

HA! yeah, that'll do it! forgot that mode() can be used to set modes as well as get them. thanks much! -murat On Sep 27, 7:10 pm, jim holtman wrote: > How about this: > > > m <- matrix(c(0, 1, 1, 0), ncol = 2) > > mode(m) <- 'logical' > > m > >       [,1]  [,2] > [1,] FALSE  TRUE > [2,]  TRUE

Re: [R] dimension-preserving matrix coersion

How about this: > m <- matrix(c(0, 1, 1, 0), ncol = 2) > mode(m) <- 'logical' > m [,1] [,2] [1,] FALSE TRUE [2,] TRUE FALSE > On Sun, Sep 27, 2009 at 6:59 PM, Murat Tasan wrote: > i've written a function to coerce a matrix (e.g. from numeric to > logical), but i'd like to know if someo

[R] dimension-preserving matrix coersion

i've written a function to coerce a matrix (e.g. from numeric to logical), but i'd like to know if someone has a more elegant method for this: > m <- matrix(c(0, 1, 1, 0), ncol = 2) > m <- as.logical(m) > m [1] FALSE TRUE TRUE FALSE i'd like 'm' to still be a matrix with the original dimensions.
