The measurement is performed in the dimuon decay channel with the ALICE apparatus in the centre-of-mass rapidity intervals $-4.46 < y_{\\rm cms} < -2.96$  (Pb-going direction) and $2.03 < y_{\\rm cms} < 3.53$ (p-going direction), down to zero transverse momentum ($p_{\\rm T}$). The J/$\\psi$ and $\\psi$(2S) production cross sections are evaluated as a function of the collision centrality, estimated through the energy deposited in the zero degree calorimeter located in the Pb-going direction. The $p_{\\rm T}$-differential J/$\\psi$ production cross section is measured at backward and forward rapidity for several centrality classes, together with the corresponding average $\\langle p_{\\rm T} \\rangle$ and $\\langle p^{2}_{\\rm T} \\rangle$ values. The nuclear effects affecting the production of both charmonium states are studied using the nuclear modification factor. In the p-going direction, a suppression of the production of both charmonium states is observed, which seems to increase from peripheral to central collisions. In the Pb-going direction, however, the centrality dependence is different for the two states ':' the nuclear modification factor of the J/$\\psi$ increases from below unity in peripheral collisions to above unity in central collisions, while for the $\\psi$(2S) it stays below or consistent with unity for all centralities with no significant centrality dependence. The results are compared with measurements in p--Pb collisions at  $\\sqrt{s_{\\rm NN}} = 5.02$ TeV and no significant dependence on the energy of the collision is observed. Finally, the results are compared with theoretical models implementing various nuclear matter effects.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.100166.v1/t1","@type":"Dataset","description":"The $p_{\\rm T}$-differential inclusive J/$\\psi$ cross sections for six centrality classes
