I am very new to R. How do I do a cross join in R? I have two tables and I want to create a new table from a cross join where each row of table 1 is copied across every row of table 2. Example below:
  Table 1      Table 2       Result
  a  b  c      d  e  f       a  b  c  d  e  f
1 x1 x2 x3   1 y1 y2 y3    1 x1 x2 x3 y1 y2 y3
2 x4 x5 x6   2 y4 y5 y6    2 x1 x2 x3 y4 y5 y6
3 x7 x8 x9   3 y7 y8 y9    3 x1 x2 x3 y7 y8 y9
                           4 x4 x5 x6 y1 y2 y3
                           5 x4 x5 x6 y4 y5 y6
                           6 x4 x5 x6 y7 y8 y9
                           7 x7 x8 x9 y1 y2 y3
                           8 x7 x8 x9 y4 y5 y6
                           9 x7 x8 x9 y7 y8 y9
