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_Name),beside=TRUE,legend=rownames(comparisons_new$Sub_Exp_Name),col=rainbow(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.
Please help,
Brinda
