GAM
...the package "faraway" by using
the generalized additive model. it shows the following error. Can some one
suggest me the right way?
library(faraway)
data(motorins)
motori <- motorins[motorins$Zone==1,]
library(mgcv)
>amgam <- gam(log(Payment) ~ offset(log(Insured))+
s(as.numeric(Kilometres)) + s(Bonus) + Make + s(Claims),family = gaussian,
data = motori)
Error in smooth.construct.tp.smooth.
spec(object, dk$data, dk$knots) :
A term has fewer unique covariate combinations than specified maximum
degrees of freedom

Time Series
I have what I hope is a simple question - is it possible to do time series
analysis on a small data set specifically only four data points?
I have collected human threat data (mean number of threats per kilometre
walked/ survey) every 3 months in eight different sites (four with an
experimental element and four control sites). I am trying to determine the
best way to determine if there is a trend in the data though from what I''ve
seen of TSA, our data set is too small. I did a simple paired t-test...

4D stacked column chart, Excel -> R
...ion (there are some chart pictures as well)....
http://www.mrexcel.com/board2/viewtopic.php?t=187336&highlight=stacked+column
because I still couldn't solve that problem I came to R.
The chart should be actually a 3D chart of the type 3D Column Chart with following achsis:
X Achsis: driven kilometre in 10000 blocks
Y Achsis: Production month
Z Achsis: number
I need to show another month in that chart, the repair month.
Each column should be a stacked column with more colors, so that every color shows one repair month.
I tried to do it with the scatterplot3d function after I saw this example...
