[R] parsing strings between [ ] in columns

Dear all, I have a data.frame with a column like the x shown below myDF-data.frame(cbind(x=c([[1, 0, 0], [0, 1]], [[1, 1, 0], [0, 1]],[[1, 0, 0], [1, 1]], [[0, 0, 1], [0, 1]]))) myDF x 1 [[1, 0, 0], [0, 1]] 2 [[1, 1, 0], [0, 1]] 3 [[1, 0, 0], [1, 1]] 4 [[0, 0, 1], [0,
