Hello All,
I have the following data set:
all
          [,1]      [,2]
[1,] 297.04115 286.34645
[2,] 303.94056 270.81590
[3,] 297.87190 290.48009
[4,] 305.81938 304.26238
[5,] 294.92061  92.14025
[6,]  72.09721 304.83084
[7,]  66.53062 279.65700
[8,] 218.46609 318.90179
[9,] 306.55251 295.80110
[10,] 278.48156 269.71947
[11,] 201.24514 277.66272
[12,] 303.93334 296.89303
[13,] 295.89849  81.98786
[14,]  46.82938  74.70764

I would like to plot(all[,1],all[,2]) when all[,2]>200. The answer, I am guessing, is embarrassingly simple but I simply cannot figure it out. Please
help me.

Logical indices on "x" and "y"

plot( all[ all[,2]>200, 1], all[ all[,2]>200, 2] )

I know this is tempting the Fates, untested, but too simple to be wrong.
