R help - Apr 2014 - Box plot without original data

Hi to everyone!

I need to plot a box plot but I don't have the original data, is it possible
to make it just with the median, mean, sd and range of values?

Any idea is welcome.


Thanks in advance.

Hi to everyone


To simulate data I only know this command:

rnorm(n , mean, sd)
?
It exists another way to specify?Median and range as well?

The point is that?I have ?this information about the variable:


Median: 4.3
Mean: 4.2
SD: 1.8
Range: 0-8

and I need a boxplot, but I don't have the original data, simulating data?
looks?a good idea to solve it.

Thanks in advance.

Hi Teresa,
You can get the return value from the boxplot function and then 
substitute the values you want into the $stats component. Then pass that 
to the bxp function. See the help pages for boxplot and bxp.

Another option is to use the box.heresy function in the plotrix package, 
as that function does not assume that the box will be defined by the 
median and (approximate) quartiles.
