[R] RES: time series interpolation

[Filipe Leme Botelho]

Hi Tom,

At least to me it´s hard to picture what´s wrong without further details regarding your data. I use spline/linear interpolation of time series regularly, so maybe this example help you out.

> ci_x
[1]   1   4  69 131 194 256 320 382
> ci_y
[1] 0.1211 0.1213 0.1233 0.1241 0.1250 0.1254 0.1255 0.1255
>
> approx(x=ci_x, y=ci_y, n=ci_x[length(ci_x)])$y


Regards,
Filipe.

Assunto: [R] time series interpolation

Hi there,
I´ve got a datatable in R which I try to interpolate with this and get the
Error below: 

> new$temp<- approx(w03_11temp$temp, n = (nrow(w03_11temp)*5))$y

Error in new$temp <- approx(w03_11temp$temp, n = (nrow(w03_11temp) * 5))$y : 
  Object of type 'closure' not registered

Any idea?? Thanks a lot.
