Hi:
Firstly, your dplyr code to generate the summary data frame is unnecessary and
distracting, particularly since you didn't provide the input data set; you are
asked to provide a *minimal* reproducible example, which you could easily have
(fun.data=mean_cl_normal,conf.int = .99, geom=errorbar,
width=0.2)
Thanks,
Mohan

Hi,
I want to plot a line graph using this data. IDX is x-axis and V1 is y-axis. I
also want standard error bars and 99% CI to be shown. My code is given below.
The section that plots the graph is the problem. I don't see all the points in
the line graph with error bars. How can I also show
back to your code to see which library it
used to load.

Well, when the error message says argument 'lx' is missing, with no
default, it really means that argument 'lx' is missing, with no
default. Your panel function has an argument 'lx', which you forgot to
change to 'ly' as you did with the prepanel function.
Hope that helps...

Hi Tim,
there are a couple of problems in your example.
(1) The most important is that your 'x' values for the matplot
are 1:5 (that is row numbers of your mat1 matrix)
and are seq(20,100,20) (that is, your vect vector) for your error bars.
Error bars are thus plotted outside the plotting
