[R] HTML nsmall vector format problem

[Short, Tom]

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.
