mobilityIndexR measures mobility in a population by generating transition matrices and calculating mobility indices.
# Install the development version from GitHub:

devtools::install_github("bcmullins/mobilityIndexR")Let’s use one of the built in datasets to create a transition matrix:
library(mobilityIndexR)
data("incomeMobility")
getTMatrix(dat = incomeMobility, col_x = 't0', col_y = 't5', type = 'relative', probs = TRUE, num_ranks = 5)
#> $tmatrix

#> 1 2 3 4 5
#> 1 0.152 0.040 0.008 0.000 0.000

library(mobilityIndexR)
data("incomeMobility")
getMobilityIndices(dat = incomeMobility, col_x = 't0', col_y = 't5', type = 'relative', num_ranks = 5)
#> $average_movement
#> [1] 0.64

#> $os_far_bottom
#> [1] 0.04
#>
#> $os_far_top
#> [1] 0.4
#>
#> $os_total_bottom
#> [1] 0.24
#>
#> $os_total_top
#> [1] 0.4

#> $prais_bibby
#> [1] 0.464
