var2fact {rgr} | R Documentation |
Rearranges data from a matrix or dataframe into a matrix where data are tagged by their variables names as factors. Used to concatenate data for display with functions tbplot.by.var
and bwplot.by.var
.
var2fact(xmat)
xmat |
name of the n x m data matrix or dataframe to be processed. |
If the data for only some of the variables available in an attached matrix or dataframe are to be processed use the cbind
construct. Thus, temp.mat <- cbind(varname1, varname3, varname6, varname8)
.
xx |
a n * m by 2 matrix where each of the n * m rows contains a value that is paired with its variable name as a factor, see Note below. |
The m
variables for n
cases results in a n * m
by 2
matrix, where [1:n, 1]
contains the variable name for value[1]
and [1:n, 2]
contains the values for the n rows in the first column of xmat
. Then rows [n+1:2n, 1]
contain the variable name for value[2]
and [n+1:2n, 2]
contain the values for n
rows in the second column, and so on.
