...atos de un servidor. El proceso es hacer una consulta en la base de datos, que me dice uqe columnas tengo que coger. Una vez hecha dicha consulta, abrir un csv, coger las columnas que me indicaba esa base de datos y subir el dato concreto del csv a una base de datos. Estoy pensando en usar Apache Flume o similar, pero es en un servidor Windows. ?Que opciones me recomendais? Gracias Jes?s [[alternative HTML version deleted]]

Hello, For several years I've been experiencing an intermittent Samba error when running a very intense, highly parallel build/compile jobset. A file is reported as "not found" even though it most certainly exists and re-running the compile jobset always succeeds. Samba version is 3.6.4 running on CentOS 5.8 with 64-bit kernel 2.6.18-308.4.1.el5. Windows side is 64-bit Window

...of the viewer window. Here is the script I am using: > png("Compare.png") > plot(compare$DepthSLI, compare$DischargeSLI, col="blue", xlab = "Average Water Depth (cm)", ylab = "Discharge (m^3/s)", xlim=c(5,40), ylim=c(0.03,0.1), main="Discharge in Flume 1") > dev.off() null device 1 When I do this R simply produces an empty file that produces an error message when I try to open it. I have tried this same script with every file format available under help(device) all with the same result. I am running Ubuntu 8.04 so I unable to s...

Hello there, I have a fairly simple request (I hope!) I have produced a filled contour plot like this: library(grDevices) library(gplots) library(plotrix) filled.contour(contour, axes=F, frame.plot=TRUE, color=terrain.colors, ylab= "Length Along Flume (m)", key.title = title(main="Velocity\n(m/s)"), key.axes = axis(4, seq(0, 0.6, by = 0.1)), asp=2, plot.axes = { axis.mult(side=1,mult=0.005,mult.label="Width (cm)") axis(side=2, at=x, labels=colnames(contour)) }) Note the asp=2 argument. I would like to make this plot tw...

I am attempting to create a contour plot using R with this code: > contour <- as.matrix(read.csv("contour.csv", row.names=1, header=TRUE)) > library(gplots) > filled.contour(contour, main="Flume 1 Flow Velocities") Now this produces the image/plot that I am looking for perfectly. However, the both axes only go from 0 to 1 instead on of using the row and column names. To rectify this I tried this: > filled.contour(contour, axes=FALSE, frame.plot=TRUE) > matrix.axes <- functi...
