R help:
...out saving workspace
4: exit R saving workspace
The portion of the code that is giving me problems is:
if(length(which( interp.depth == highres.depth[i] )) >0 ) {
print(paste("depth = ",highres.depth[i],sep=""))
depth.tracker <- c(highres.depth[i],depth.tracker)
caco3.interp.vector <- c(mean(caco3.interp),caco3.interp.vector)
caco3.interp <- numeric(0)
}
When the routine misses a depth, it returns a length of zero for (say)
depth = 1.4, or highres.depth[141]. but when i type in the value 1.4,
I get the proper answer. Any idea what is going on he...

fivenum accuracy (PR#13164)
Full_Name: David Leong
Version: 2.7.2
OS: Windows XP
Submission from: (NULL) (12.187.86.2)
It appears for the fivenum function, there is a strait average between two
ranked samples. This should be a linear interpolation between ranks.
For the following data set
#data
CaCO3<-c(130.8,129.9,131.5,131.2,129.5,132.7,131.5,127.8,133.7,132.2,134.8,131.7,133.9,129.8,131.4,128.8,132.7,132.8,131.4,131.3)
fivenum reports 127.80 130.35 131.45 132.70 134.80
130.35 should be 130.125. The other are correct.
For the 20 points, the rank is (20+1)/4=5.25 so the weighting factor...
