ANOVA with mean and SD?

[Wolfgang Schechinger]

Dear experts, 

I need to analyze 2500 parameters in 3 groups by ANOVA, means I want to detect 
which parameters vary between the groups. 

For every group I have a table with 

number of data points (may vary from group to group)
mean
standard deviation. 

(3x3 columns, 2500 rows)

As I understand the anova(y,g) function, one needs to supply the raw data and 
there should be the same number of data points per colum at least for each 
parameter.

Is there a way to adapt the function to my data set, or is there another 
function one could use?

What can I do when my data does not follow a normal distribution?

Many thanks for your help!

Wolfgang
