How do I add a numeric class to a data .frame.
For example, I have calculated the following probabilities
1 2 3
0.0011566127 0.0009267028 0.0081623324
How would I add them back into my data.frame for example
My_df <- data.frame(col_1 = c('A', 'B', 'C')) such
that I end up with
col_1 col_2
A 0.0011566127
Though I could use a cbind.

The obvious answer is My_df$col_2 <- prob_result but whether that would work might depend on the structure of prob_result. What does dput(prob_result) return?

[R] Adding a numeric class to a data.frame
Jeff R, it would be helpful if your intent was understood.
For example, did you want output as a column of labels c("A",
"B", "C") and
another adjacent of c(0.0011566127, 0.0009267028, 0.0081623324) then you
could do:
data.frame(labels=c("A", "B", "C"),
data=c(0.0011566127, 0.0009267028,
0.0081623324))
labels data
1 A 0.0011566127
2 B 0.0009267028
3 C 0.0081623324
If you wanted your columns labeled with the data in multiple columns, try
this:
> result <- data.frame(t(c(0.0011566127, 0.0009267028, 0.0081623324)))
> result
X1 X2 X3
1 0.001156613 0.0009267028 0.008162332> names(result) <- c("A", "B", "C")
> result
A B C
1 0.001156613 0.0009267028 0.008162332
But these are not solutions to your specified problem unless you explain
properly what you want to do and the exact expected output.
