R help - Nov 2007 - better curve

Hi R users,

I have collected data which I plot(x,y).The problem it has oscillations.
Now i'm trying to "make better" this curve with a smooth line
starting let's
say @x=300 s.
And then collect my new datas.
But I don't know how doing this.

Perhaps a linear regression ??

Thanks for any help it will be given.

Hello Mysimbaa,

If you want to fit a smooth line to your data, there are many ways to do 
it.  One option is to use splines.  See the smooth.spline() function. 
If you only want to add a line to highlight the trend in your data, that 
should be enough.  But if you want to do more serious analytical work, 
it is probably a good idea to learn about the different methods, its 
assumptions and limitations.
