Standard Error Calculation

[Vivek]

Hello Everyone,

I am a big fan of Deducer!

I am using the errorbar geom and want to calculate the standard
error. I choose summary and then custom. I am suppose to input the
'y function', the 'y-min function', 'the y-max function', 'the data
function.'

Can anyone help me with how I should input these functions? I know
the formula for Standard Error, but am not quite sure how to input a
function into Deducer to calculate these functions.

thanks,
Vivek

Vivek,

you will want

function(x) mean(x)

function(x) mean(x) - sd(x)/sqrt(length(x))

function(x) mean(x) + sd(x)/sqrt(length(x))

and don't put anything in the data function box.

see the attached plot for an example.

Cheers,
Ian
