Dear R-users, I have following data # Plot coloured scatter plot c<-dat[100:110,c(5,7,8)] par(mfrow=c(3,2)) plot(c$lb,c$index, pch=1, col=5,cex=1, lwd=2, xlab="LB", ylab="Index",cex.main =1,font.main= 1, main="scatterplot") ID index lb 100 FLINDYTHNIPLI 1.84770221 9.087463 101 none 0.06657547 8.927778 102 GDDKVYSANGFTT -0.22922544 8.599913 103 GDFTQGPQSAKTR 0.01203925 8.483816 104 GDKEFSDALGYLQ -0.06264494 8.463524 105 GDPTETLRQCFDD -0.10011148 8.483816 106 GDSGGSFQNGHAQ -0.13460447 8.442943 107 GDVYSFAIIMQEV 1.91504700 8.413628 108 GLRSLYPPPPPPQ -0.11224126 8.383704 109 GLWVTYKAQDAKT 0.03723291 8.257388 110 GMSQPLLDRTVPD -0.06580206 8.294621 When I plotted a scatter plot of index against lb, there are two extreme values. How can I plot so that these values are replaced by their ID or the IDs are next to these values on the graph? I want to do something like: if index > 1.5 then plot the IDs instead of the indexes greater than 1.5 or place the Ids next to their indexes. The data above is a little part of my real data (which might have more than two extreme outliers). Thanks for your help, Jenny
