Proper Paste for Data Member
I imported a spreadsheet into a variable sh
e.g. sh$aaaa, sh$bbbb, etc...
doing the following:
tsSource <- ts(paste("sh$",NAMEVARIABLE,sep="") ... )
fails. The paste isn't evaluating properly. What is the proper way to
concatenate a data source with a member name such that they evaluate
properly.
actual code below:
doEnv <- function(SOURCEDATA,REGDATA,HOUR,ENVNAME,REP...

Trouble Highlighting outliers on Time Series Plot
...Give then following code:

# find STL Outliers by weight and append sh2, use Robust

tsSourceIO <- which(tsSourceDiag $ weights < 1e-8)

Getting a date out of an indice in a time series
I have a weekly data set imported via:
tsSource=ts(sh1$I000,start=c(2004,1),freq=52)
I am now getting to some 'spit and polish' but I realize something I can't
wrap my head around.
Given an outlier I find at say tsSource[54] ... how can get translate index
54 into the date\week. I mean I can figure out obviously that entry 52 is

[Solved][Code Snippets] Dropping Empty Regressors
...a level shift but I do what I can.) So here
is the code snippet that finally let me pre-check my regressors and drop any
of them that were all true or all false.
First the automagic STL outlier grabber that caused part of the problem:
############################################################
# tsSource being my time Series source.
# sh2 is a table of all my regessors that have been previously pulled in
# this has historic and future values in it also, it gets sliced later.
# the EOM is the regessor holding weeks that contain an 'End of Month'
#
# This appends the found IOs to the regress...
