How to access the table values in R?
Sometimes we want to extract table values, especially in cases when we have a big table. This helps us to understand the frequency for a particular item in the table. To access the table values, we can use single square brackets. For example, if we have a table called TABLE then the first element of the table can accessed by using TABLE[1].
Example1
x1<−rpois(200,5) x1
Output
[1] 10 7 6 4 3 8 4 5 4 4 2 8 7 5 3 5 3 5 3 9 7 5 8 4 2 [26] 7 6 6 5 3 11 3 5 8 7 6 3 5 6 1 3 7 8 4 6 6 3 6 7 6 [51] 14 3 3 3 8 9 4 3 9 2 8 5 2 2 3 8 4 3 3 6 5 6 6 5 5 [76] 5 4 3 1 6 11 9 10 7 6 4 4 5 8 4 4 2 6 6 7 5 3 5 3 4 [101] 5 2 6 6 5 6 2 5 5 6 3 4 5 4 16 5 2 0 2 5 5 5 2 4 3 [126] 6 3 3 2 3 5 5 6 3 7 4 5 7 4 7 5 6 5 5 6 11 3 2 7 4 [151] 4 5 7 4 9 6 4 1 4 8 4 3 3 10 7 4 8 5 4 9 5 6 3 2 4 [176] 8 4 5 7 4 6 5 5 1 7 4 7 6 5 4 7 9 3 11 5 6 4 4 3 4
