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.
Please help,
Brinda
