[R] adding a column to data frame solving the replacement problem

I have a data set (mydata) containing 471 variables. One of the columns looks as below
$ Sequence : Factor w/ 3 levels "","%Seq%gre",..: 2 2 2 2 2 2 2 2 2 2 ...
sequence contains %Seq%gre and %Seq%tse and I extract only %Seq%tse and add it to my variables and plot a scatterplot of mydata. I use table and the result is: table(mydata$Sequence)
1 25520 243744
in the next step I want to add a column to my main data set (mydata) containing only %Seq%tse, however when I use the following command there's an error telling me:
Error in `$<-.data.frame`(`*tmp*`, "NewColumn", value = c(3L, 3L, 3L, :
replacement has 243744 rows, data has 269265
How can I add this column correctly to mydata?
Thanks for any help
