Hi, I have sucessfully plotted the graph by using the following command: ec<-rep(0,length(e)) fc<-rep(0,length(f)) plot(e,ec,type="p",col=1,pch=19) points(f,fc,col=2,pch=20) legend(1.0e+08,1.0,c("dog", "human"),text.col="green4",pch=c(19,20),col=c(1,2)) Below are the values for e and f...the questions is how am i going to adjust the scale width of my x-axis and my y-axis will start at 0?? Any suggestion?? thanks in advance!! e: [1] 17358865 17966995 21306539 27880531 34166504 36111044 36266288 [8] 36854306 43786190 44322336 45529444 46302360 53479132 58567262 [15] 60564442 72637088 79875476 93155112 94372260 96643396 103123936 [22] 116908456 131781664 132968364 135945080 141788832 149924864 156539568 [29] 157817896 162399496 168344072 173146584 176302744 182878168 183946152 [36] 185068720 190791232 NA
