Call:
lm(formula = as.matrix(ydata) ~ as.matrix(xdata))
Coefficients:

i've tried converting xdata and ydata to data frames but i still get
errors.
simple3<-function(xdata,ydata)
{
xdata<-as.data.frame(xdata)
ydata<-as.data.frame(ydata)
ofit<-lm(ydata~xdata)
list(ofit)
}
i.e.
> simple3(xdata=x,ydata=y)
Error in model.frame(formula, rownames, variables, varnames, extras,
extranames, :
invalid variable type
please help!...
