Dear developers, I found a small typo in the german translation for the aggregate() function: In the string "keine Zeile f?r die Aggragation" it should be spelled 'Aggregation' instead of 'Aggragation' (e instead a). After a quick look into the sources, I found two places for it: #grep -r -e "Aggragation" * src/library/stats/po/R-de.po:msgstr "keine

Have 40,000 rows of buy/sell trade data and am trying to add up the buys for each second, the code works but it is very slow. Any suggestions how to improve the sapply function ? secEP = endpoints(xSym$Direction, "secs") # vector of last second on an XTS timeseries object with multiple entries for each second. d = xSym$Direction s = xSym$Size buySize = sapply(1:(length(secEP)-1),

Hi R experts, I need know how calculate a weighted mean by group in a data frame. I have tried with aggragate() function: data.frame(x=c(15,12,3,10,10),g=c(1,1,1,2,2,3,3),w=c(2,3,1,5,5,2,5)) -> d aggregate(d$x,by=list(d$g),weighted.mean,w=d$w) Generating the following error: Error en FUN(X[[1L]], ...) : 'x' and 'w' must have the same length Thanks in advance [[alternative HTML vers...

...ou have a select list of all the U.S. states and the user can make multiple choices. How do you grab all those choices into the database and they would be used for queries. I was reading up on serialize() but the warning in AWDWR is that it doesn''t work well for queries. Also composites / aggragates seems a bit much, maybe not. I know in the past I''ve used addtional tables as example. Tavels_table - id, user_id States_table - id, travel_id, state id, travel_id, state...

...le option). On startup, collection of data is disabled. To begin collecting data use the smbcontrol program to turn on profiling (see the smbcontrol man page). Profile information collection can be enabled for all smbd processes or one or more selected processes. The profiling data collected is the aggragate for all processes that have profiling enabled. With samba compiled for profile data collection, you may see a very slight degradation in performance even with profiling collection turned off. On initial tests with NetBench on an SGI Origin 200 server, this degradation was not measureable with pro...

Dear all, When I use aggregate function as: attach(warpbreaks) aggregate(warpbreaks[, 1], list(wool = wool, tension = tension), sum) The results are right but I get a warning message: "number of items to replace is not a multiple of replacement length." BTW: I use R version 2.4.1 in Ubuntu 7.04. Your kind solutions will be great appreciated. Best wishes Yours, sincerely, Xingwang
