[R] Data.frame Question

2010-03-11 Thread GULATI, BRIJESH (Global Markets FFO NY) 


   Hi: 
   I want to add a constant to an existing col of the
 data.frame. I have the following dataset:
 
 
   structure(list(x = c(1, 1, 1, 1, 1), y = c(1, 1, 1, 1, 1)),
 .Names = c(x, 
   y), row.names = c(NA, 5L), class = data.frame)
 
 
   I want to add a constant to col 1 and col 2 to get the following
 data.frame 
 
   structure(list(x = c(2, 2, 2, 2, 2), y = c(3, 3, 3, 3, 3)),
 .Names = c(x, 
   y), row.names = c(NA, 5L), class = data.frame)
 
 
   Thanks, 
   Brijesh

[R] data.frame question

2010-03-07 Thread joseph 
hello

can you show me how to create a data.frame from two factors x and y. column 1 
should be equal to x and column 2 is 1 if it is common to y and 0 if it is not.

x=factor(c(A,B,C,D,E,F,G))
y=factor(c(B,C,G))

the output should look like this:
A0
B1
C1
D0
E0
F0
G1

Thanks 
Joseph Dhahbi
