Hi...sorry that my question seemed incomplete. The plotting code : par(cex.axis=0.8,las=1,font.lab=2,font.axis=2,family="sans",mgp=c(2,1,0),mar=c(3, 3, 4, 2)+0.1) plot(A$pos,-log(A$GPVI_frequentist_add_Batch_expected_pvalue,10),col=A$R2class,pch=A$pch,xlim=c(161160087,161214038),ylim=c(0,7),xlab="Genomic position",ylab=expression(-log[10]~(P-value)))
I am using a MacBook Pro and I have the R 2.15.0 . I have used only the base-graphics and not loaded any other libraries. Hope that completes the question. Please also find the plot attached here. Note the y-axis label is not in bold face or in "sans" font. Regards, Aparna.
