Hello, How would you export a 3-dimensional array to an SQL database? a<-array(1:24, 2:4) Is there an open source DB that would be more adequate for this type of operation? Is there a way to reshape/flatten a 3-dimensional array?

Hello, How do you change the language of the labels in a graph. In this example, I want to get French labels by changing Sys.putenv. I should get "Mai" instead of "May". Sys.putenv(LANGUAGE="fr") x <- as.Date(c("1jan1960", "2jan1960", "31mar1960", "30jul1960"), "%d%b%Y") y <-1:4 plot(x,y) Regards, Pierre

Dear all, I'd appreciate any hints how to arrange some plots. I have three plots. I would like to arrange them in the following order: - Plot 1 and Plot 2 should be in the upper row - Plot 3 should be in the lower row but centered in the middle. I hope the following sketch will help understanding my problem ================ | === === | || P1| |P2 | | || | | | | | === === |

Hello, Let's say I have 50 R scripts to run. What would be the most efficient way to run them? I thought I could do multiple Rterms in a DOS batch file: Ex: Rterm <1.R> 1.txt Rterm <2.R> 2.txt ... Rterm <50.R> 50.txt However, I'm afraid they will all open at the same time. I know I could pause the batch file with something like: PING 1.1.1.1 -n 1 -w 60000

Hello, I'm trying to get a few turnpoints for a financial time series. There is a function in pastecs that does that. However, I get a large number of turnpoints: library(pastecs) data(EuStockMarkets) dax <-EuStockMarkets[,1] plot(dax) turnp <-turnpoints(dax) summary(turnp) #gives 925 peaks/pits!!! How can specify to get only 30 turnpoints? Second question: the extract function
