Hi,

I have a huge data table with several variables containing missing values. I
want to make a simple scatter plot (Mass, HSI) and draw a smooth regression
on it.

Here are the summaries of these two variables:

> summary(Mass)
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max.
   46.0   205.9   272.5   282.6   348.3   610.1

> summary(HSI)
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max.    NA's
  0.300   1.045   1.350   1.491   1.835   4.270  13.000

So there are 13 missing values in HSI.

I did
plot(Mass,HSI)

and it worked fine. However, when I wanted to draw the smooth regression,

scatter.smooth(Mass,HSI)

I got this error:

Error: NA/NaN/Inf in foreign function call (arg 1)

I did not forgot to load the package modreg...

Must I declare the "NAs" before doing this analysis? If so, how?

Thanks,

Sébastien Plante
