Hi,
Many apologies for sending this twice. I accidentally hit the send button before I finished writing my mail. I am new to R and I hope someone can help me with my problem. I am trying to draw a side by side barplot. There is a main experiment and there are many sub experiments within the main experiment. I would like to draw a bar plot showing the number and type of sub_experiments done for each main_exp. For instance if the Main_Exp is 6, I would like to group the sub exp's for the main_exp and show that there were two sub_exp's done an ELISA and a FCM and that the ELISA was done once and the FCM was done twice. Similarly for Main_Exp 7 I would like to show that for there were ELISA,FCM,qPCR,Telometry done and that they had a count of 3,3,2,5 respectively. This is what my dataset looks like: Main_Exp_Name Sub_Exp_Name Sub_Exp_Count 1 ELISA 2 6 ELISA 1 6 FCM 2 7 ELISA 3 7 FCM 3 7 Telometry 2 7 qPCR 5 The code that I have is table(comparisons_new) barplot(as.matrix(comparisons_new$Sub_Exp_Count),xlab="Main_Exp_Name", ylab="Sub_Exp_Count",ylim=c(0,10),names.arg=(comparisons_new$Main_Exp_Na me),beside=TRUE,legend=rownames(comparisons_new$Sub_Exp_Name),col=rainbo w(5)) With this code, I am able to draw the barplot, but am having issues: I am not able to group them together. That is for each Main_Exp I am not able to group the Sub_Exp's under it. It all shows up as one continuous barplot without any spaces in between the Main_Exp's. Also, I would like to be able to use the same colour for a particular sub_Exp_Name no matter in which ever Main_Exp it may show up. But, this is not working for me.
