Dear all, I admit this is not anything to do R and even with Statistics perhaps. Strictly speaking this is a math related question. However I have some reasonable feeling that experts here would come up with some elegant suggestion to my question. Here my question is: What is sum of all Integers? I somewhere heard that it is Zero as positive and negative integers will just cancel each other out.

I am not a pure Statistics background and therefore please forgive me if this question (which is not R related either) is too trivial. In many Statistics literature I find following statement: "restrictions in different coefficients matrices have to be imposed to ensure uniqueness of the parametrization". Can somebody tell me what is the meaning of Uniqueness in the parametrization?

Dear all R users, I am wondering is there any procedure exists on R to fetch data directly from "http://www.ncdex.com/Market_Data/Spot_price.aspx" and save it in some time series object, without filling any field in that website. Can somebody point me whether it is possible? Thanks and regards, [[alternative HTML version deleted]]

Dear all, being a relative beginner in R, I apologize for posting the second question within two days. So I want a stacked barchart, which should look like the one produced by this code: Tuvalu <- c(9,3,4,0,3,0,0) Singapor <- c(38,0,0,0,12,19,0) Samoa <- c(26,16,2,0,5,2,0) PNG <- c(56,4,0,5,2,0,56) Micronesia <- c(6,0,0,0,0,0,0) graph4 <-

Dear all, I am trying to add a value to a dataframe and name the row with a number.? I have tried row.name, rowname, and attr(x,"row.names") but none seem to work.? It seems like it should be simple, so not sure why I can't get it to work.? Any suggestions? Thanks, Tim x<-seq(1,20,2) y<-seq(20,1,-2) xy<-data.frame(x,y) xy<-rbind(xy,c(0,0)) #Threeattempts that

hi, anyone to know a tool that will display more friendly output ... probably a tree like structure (if no cross sections occur)... OR a top like output... thanx raptor _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Dear List, I am trying to plot date vs. time, but am having problems getting my y-axis labels how I want them.? When left on its own R plots time at 6 hour intervals from 03:00 to 23:00.? I am wanting 6 hour intervals from 2:00 to 22:00.? I realize yaxp doesn't work in plot(), so I am trying to get it to work in par().? However, now I get the ticks where I want them but the time is output

Dear List, ? I am creating a boxplot with two subsets, very similar to the example by Roger Bivand at ?boxplot (reproduced below).? I am trying to change the labels on the x-axis to have one number to cover both subsets.? I can do this in other plots by using axis=FALSE followed by a separate axis() command.? I have also tried variations in the names= argument but can't get it to work.?

Dear List, I have a series of dates and I am needing to know the greatest length of continuous dates - i.e. the number of dates before a break in the series.? For example, below there are three continuous series of dates with lengths 4, 6, and 8.? How can I count the number of continuous dates?? rle() will do it for constant integers, but I can't figure a way to modify it for continuous

Hi All, After much searching and head scratching I post you this! I can''t seem to find a generic way to handle multiple select data.
