Hello R-Experts, Currently I'm using "RBloomberg" package in R-2.2.1 in Windows machine ( XP). When I'm running one specific example using blpGetData given in help file I'm getting the following error message. conn <- blpConnect() edb <- blpGetData(conn, "ED1 Comdty", "PX_LAST", start=chron("1/1/06"),

Together with Enrique's running start and Prasad's work, we figured out how to get tick data and bulk data from Bloomberg into R. Here is a code snippet which builds on Enrique's. ---------------------------- require("RDCOMClient") blCon <<- try(blCon <- COMCreate("Bloomberg.Data.1"), silent=TRUE) # Always check the class of blCon before proceeding! #

Dear R users, x-values (EI) = Adw, EG1, LA1, Ad1, LA2, LA3...(14 levels, insect stages) y-valus = antpop within the boxplot function x-values are ordered alphabetically Idea: x-values ranked by list order (insect stage: Egg stage 1 is followed by Larvae 1 and not by Egg stage 2 as it would be in an alphabetically order) Problems with the order(tapply()) function: variable lengths

Dear R Users, For running wavelet functions using dwt( ), modwt( ), and mra( ), a wavelet filter algorithm is applied. For all these functions, default is "la8" and other possibility is "haar". In related documents, another possibilities like as symlet and coiflet ... are not cited. Besides "la8" and "haar", which wavelet filters can be used? Thank
