We present results of a search for like-sign dielectron plus multijet events using 107 pb{sup -1} of data at {radical}s = 1.8 TeV collected by the CDF experiment. Finding no events that pass our selection criteria, we set 95% confidence level upper limits on gluino-gluino ({tilde g}{tilde g}) and squark-squark ({tilde q}- {anti {tilde q}}) production with R parity violating decays of the charm squark ({tilde c}{sub L}) in {tilde g} {yields} c{tilde c}{sub L} and of the lightest neutralino ({tilde {xi}}{sup 0}{sub 1}) in {tilde q} {yields} q{tilde {xi}}{sup 0}{sub 1} via a non-zero {lambda}`{sub 121} coupling. We compare our results to NLO calculations of gluino and squark production cross sections and set lower limits on the masses M({tilde g}), M({tilde t}{sub 1}), and M({tilde q}).
