convert data frame: two variables into _one_ binary variable
In R, as.logical() and other functions treat anything >0 as TRUE. Thus: Rgames> foo<-sample(0:5,10,rep=TRUE) Rgames> foo [1] 0 5 1 0 1 5 2 5 4 5 Rgames> as.logical(foo) [1] FALSE TRUE TRUE FALSE TRUE TRUE TRUE TRUE TRUE TRUE For your case, simply (womensrole$agree>womensrole$disagree) will return the logical vector you want. Just for info, In R, as.logical() and other functions treat anything >0 as TRUE. Thus: Rgames> foo<-sample(0:5,10,rep=TRUE) Rgames> foo [1] 0 5 1 0 1 5 2 5 4 5 Rgames> as.logical(foo) [1] FALSE TRUE TRUE FALSE TRUE TRUE TRUE TRUE TRUE TRUE Liviu Andronic wrote
Dear all, I am trying to convert the following data frame into a format more useful for me:
library("HSAUR2", lib.loc="C:/Program Files/R/R-3.0.2/library")
Loading required package: tools
Attaching package: ?HSAUR2?
The following object is masked _by_ ?.GlobalEnv?:
womensrole
head(womensrole)
education gender agree disagree sexe 1 0 Male 4 2 0 2 1 Male 2 0 0 3 2 Male 4 0 0 4 3 Male 6 3 0 5 4 Male 5 5 0 6 5 Male 13 7 0 In 'womensrole', how do I convert 'agree' and 'disagree' variables into one proper binary variable, say: education gender agree sexe 1 0 Male TRUE 0 2 0 Male TRUE 0 3 0 Male TRUE 0 4 0 Male TRUE 0 5 0 Male FALSE 0 6 0 Male FALSE 0 7 1 Male TRUE 0 8 1 Male TRUE 0 9 2 Male TRUE 0 10 2 Male TRUE 0 11 2 Male TRUE 0 12 2 Male TRUE 0 [..] I'm sure there is an easy way to do this (in the form of 'melt', 'cast', etc.), but I'm not sure how to approach the problem.
