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 use the assign and pa...

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 <- scatterplot3d(TotLogDisttenp,TotDifftenp,TotMeasuredRSLtenp,pch=16,highlight.3d=TRUE,angle=130,type="h",main="MRSL ~ LogDi...

...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...
