Looping through R objects with $ operator and tags
Hi all,
Suppose I want to set the values in a column to the log of the values
of another column like so:
object$LogDist <- log10(object$Distance)
How do I loop through the objects if I have object1, object2, etc to
perform this function?
object1$LogDist <- log10(object1$Distance)
object2$LogDist <- log10(object2$Distance)
object3$LogDist <- log10(object3$Distance)
I was trying to

scatterplot3d bug??
Hey guys,
Not sure if I encountered a bug with the scatterplot3d function.
Here's the calls I made:
s3d1 <- scatterplot3d(TotLogDisttenp,TotDifftenp,TotMeasuredRSLtenp,pch=16,highlight.3d=TRUE,angle=40,type="h",main="MRSL
~ LogDist + Diff");
s3d1$plane3d(fitols);
s3d1 <-

lme model specification
...complicated experiment.
The dependent measure is the estimated distance, which is measured as a
function of the actual distance. There are also several other IVs.
The plot of log estimated distance as a function of log distance is
linear. So in the rest of the analysis I will use logestimate and
logdistance.
My plan is to see how the other IVs affect the slope and intercept of
this linear relationship between logestimate and log distance.
What complicates everything is that each datum point is not independent.
Rather, many data points come from each subject.
So:
* Each subject gets many objects at...
