trellis

问题 Hello their i am getting error in this code with trellis server but it is working on other server perfectly <?php $localfile = 'test.txt'; $sftpServer = 'x'; $sftpUsername = 'x'; $sftpPassword = 'x'; $sftpPort = 22; $sftpRemoteDir = '/'; $ch = curl_init('sftp://' . $sftpServer . ':' . $sftpPort . $sftpRemoteDir . '/' . basename($localfile)); $fh = fopen($localfile, 'r'); if ($fh) { curl_setopt($ch, CURLOPT_USERPWD, $sftpUsername . ':' . $sftpPassword); curl_setopt($ch, CURLOPT_UPLOAD, true);

问题 Say I want to create an ordinary xyplot without explicitly specifying axis limits, then how are axis limits calculated? The following line of code produces a simple scatter plot. However, axis limits do not exactly range from 1 to 10, but are slightly expanded to the left and right and top and bottom sides (roughly by 0.5). library(lattice) xyplot(1:10 ~ 1:10, cex = 1.5, pch = 20, col = "black", xlab = "x", ylab = "y") Is there any way to determine the factor by which the axes were expanded

问题 I used the lattice package to draw a line plot. library(lattice) xyplot(price~month,groups=perc,data=Edf,type='l', main="Percentile chart of OpRes Charge Rates Forcast", ylab="OpRes Charge Rate ($/MWh)", xlab="Months",ylim=c(0,40),auto.key=TRUE) Then I wanted to add some dots to the existing plot. points(rep(1,length(OpResWestJan)),OpResWestJan) OpResWestJan is a vector, but the dots never appeared in the existing plot, and there were no warnings. 回答1: For the sake of completeness, here is a
