Extracting variance components from lmer
Hi All.
I need a bit of help extracting the residual error variance from the VarCorr
structure from lmer.
#Here's a 2-way random effects model
lmer.1 <- lmer(rating ~ (1|person)+(1|rater), data = dat)
#Get the structure
vc.fit <- VarCorr(lmer.1)
#results in.....
$person
1 x 1 Matrix of class "dpoMatrix"
(Intercept)
(Intercept) 0.7755392
$rater

categorical variable in scatterplot (car)
Hello R folks,
I am encountering a problem with the following scatterplot function from the
car package:
> scatterplot(y~x|z)
where y and x are continuous (interval) random variables and z is a
categorical variable. When z is a categorical variable coded 1 or 2, I
(appropriately) get a scatterplot of y by x, coded by z. Similarly, when z
is a categorical variable coded 1, 2, or 3, there is

Question about scatterplot in package car
I am getting an error message from scatterplot:

(CAR) Scatterplot and problems (?) with abline
Network Blitz
I'm trying to generate a graph to summarize Interest Rate Parity. This
involves a scatterplot of x against y where the x and y limits are set
so to center the graph on 0,0 and then adding each axis line and a 45
degree line. Using CAR's scatterplot (sample code below) everything
except the axes plot fine:

Removing default loess line from scatterplot ({car})
scatterplot() is autogenerating a regression and loess line. I want to remove

not have code that adds it (see below), so I am puzzling...

scatterplots in car package
Hi, using scatterplot in 'car' package.
There are 4 plots to be pictured together (ignore data used):
library(car)
par(mfrow=c(3,1))
ts.plot(rnorm(100))
ts.plot(rnorm(100))
scatterplot(rnorm(100),rnorm(100),boxplot="",smooth=T) # scatter with
non-parametric fit
problem is that the last one comes 'always' separate.
Is there any way to solve it?? of course can use

Scatterplot help
Hi my friends,
I'm trying to make a scatterplot like this.
1) I have a 3-variable dataset. They are ID, x, and y.
2) "x" is for the X-axis, "y" for the Y-axis, and "ID" is used to label all
the cases in the scatterplot.
3) After creating the scatterplot, I need to add both a X-axis reference
line and a Y-axis reference line. The X-axis reference line is a

smooth scatterplot and geo map
Hello everybody,
I'm trying to understand how to draw a smoothed scatterplot on a geographic
map with R.
Have a dataframe with point locations (long, lat) and was able to simply
plot these points on a shp map by using the maptools package. However,
instead of having simply the raw points on the map, I would like to have a
"smoothed" scatterplot of the same superimposed on the map.
