John, you can use format ahead of time (this converts to character
columns, so HTML won't reformat), and then use HTML:
> z=format(iris[1:2,1:2],nsmall=3)
> z[,2]=format(iris[1:2,2],nsmall=1)
> HTML(z,file="")

Hi Tom
Thanks for the reply.
I see what you are saying - that format does not format using an nsmall
vector, though the documentation (of HTML.data.frame) and the example
suggest nsmall uses a vector.
Even if I went through and changed the columns with a loop the
HTML.data.frame would reformat them according to its formatting so I
would still get all the columns with one value of nsmall.
Specifically I want 0 for my first three columns and 4 for the remaining
columns in my data frame. (I would also like to control the widths but I
guess I may run into the same problem).
I could reprocess the HTML output but that makes generating the HTML a
bit redundant!
Regards
John

John,
I don't think nsmall uses a vector. Try the following with format (which
HTML.data.frame uses):
> format(iris[1:2,1:2],nsmall=c(3,1))
Sepal.Length Sepal.Width
1 5.100 3.500
2 4.900 3.000
It looks like you'll have to do a format column by column with a loop.
