hi all
i have a function that uses two inputs, say xdata and ydata. An example
is the following,
simple1-function(xdata,ydata)
{
ofit-lm(ydata~xdata)
list(ofit)
}
say i use arbitray number for xdata and ydata such that
D =
x1 x2 y
1 1 10
2 6
There was a packaging error. A new RPM version is on its way to CRAN.
Thanks.

There was a similar question about one week ago regarding the use of
table(x,y). One approach could be to use the following:
simple1 - function(xdata, ydata){
ofit - substitute(lm(ydata~xdata))
list(eval.parent(ofit))
}
#
simple1(xdata=x, ydata=y)
lm(y~x)
I hope it helps.
