How do I plot a line followed by two forecast points?
...scaled against a new axis scale, thus the two plots are not directly comparable (I need the forecast points to be scaled according to the existing y axis). An example is pasted below. Any ideas on how to achieve this would be much appreciated. Thanking you in advance, George. # Sample dates >xValues = seq.Date(as.Date("1990-01-31"),to=as.Date("1992-12-31"),by="month"); # Sample y value > yValues<-NULL; > yValues[1:length(xValues)]=seq(0.1,length=length(xValues)) # Plot the series as a line > plot(xValues,yValues,type="l"); # Sample foreca...

Is there an lm() equivalent of panel.lmline()?
panel.lmline returns intercept and slope of y ~ x subsetted to the combination of conditioning factors given to xyplot in lattice. for instance: xyplot(Xvalues ~ log(Qvalues)|Tfac, data = df7, panel = panel.lmline) I am looking to find the equivalent formulation for lm() proper. If I do this: lmcal <- lm(Xvalues ~ log(Qvalues):Tfac, data = df7) Only one value of the intercept is returned. It appears as all the 'individual' intercepts are s...

abline(v= x) in plot with time formated xaxis not working
Hi, I try to create a vertical line in my plot, which has a xaxis comprising time formated data. This is what I tried: ---------------- y<-152833 x<-strptime(y, format="%H%M%S") abline(v=x, col="red") ---------------- for some reason, it doesn't work and no error msg is displayed... I hope someone can tell me what I do wrong, or maybe an alternative. Thanks

Data.frames can not hold objects...What can be done in the following scenario?

I have a function that takes 2 inputs and returns a vector: testfun <- function (x,y) seq(x,y,1) I have a data.frame defined as follows: testframe<-data.frame(xvalues=c(2,3),yvalues=c(4,5)) I would like to apply testfun to every row of testframe and then create a new column in the data.frame which holds the returned vectors as objects. Why do I want this? Because the returned vectors are an intermediate step towards further calculations. It would be great to k...

Plotting from a matrix, where column 1 is your x value

I've tried using row.names=1 to make the first column the value for that row (whereas before I had 1-31 sequence) and then my 1st column) but I can't work out how to tell it that column 1 of my dataset is the xvalue for the data in that row?
