How to generate boxplot

Question

I have a data and from that, I want to generate boxplot. My file is saved in \"1.txt\" file and it seems like this

R  S1G1   S1G2   S2G1   S2G2
1  0.98   0.9         


        

Answer 1

Maybe you want to reshape your data first:

x1 <- reshape(x, idvar="R", varying=list(2:5), direction="long")

And than plot it:

boxplot(S1G1 ~ R, data=x1, main = "Output result",las = 2, pch=16, cex = 1,
    col = "lightblue", xlab = "R",ylab = "SNP values",ylim =c(-0.4,1.2), 
    border ="blue", boxwex = 0.3)
