Problems with accessing double elements in a list in R
问题 I have performed a bootstrapping with 2.000 resamples of the Lee Carter model for mortality projection. The question is not specific for mortality studies, but on more general dimensions in R. After performing the bootstrapping I get a list with 2000 elements, each for every of 2.000 re-estimations of the model. For each model, there are estimates of my 3 variables: a_x, b_x and k_t. Both a_x and b_x are age-specific, so the "x" denotes an age in the interval [0:95]. I would now like to plot
