Dear all Is there an easier way to retrieve the name of an object? For example, > tmp <- 1:10 > as.character(quote(tmp)) [1] "tmp" > as.character(quote(mtcars$cyl)) [1] "$" "mtcars" "cyl" > as.character(quote(mtcars$cyl))[3] [1] "cyl" The last call more than anything seems a hack. Is there a better way? Thank you Liviu

I am trying to plot a graph but the points on the graph should be different symbols and colors. It should represent what is in the legend. I tried using the points command but this does not work. Is there another command in R that would allow me to use different symbols and colors for the points? Thank you kindly. data(mtcars) plot(mtcars$wt,mtcars$mpg,xlab= "Weight(lbs/1000)",

Hiya, Is there any reason (and anything to worry about) if disk target IDs don''t start at 0 (zero).

Hello, When plotting a barchart with ggplot it drops the levels of the factor for which no counts are available. For example: library(ggplot) mtcars$cyl<-factor(mtcars$cyl) ggplot(mtcars[!mtcars$cyl==4,], aes(cyl))+geom_bar() levels(mtcars[!mtcars$cyl==4,]) This shows my problem. Because no counts are available for factorlevel '4', the label 4 dissapears from the plot. However, I

hail, I partitioned the disk this way: fdisk da0 ******* Working on device /dev/da0 ******* parameters extracted from in-core disklabel are: cylinders=12161 heads=255 sectors/track=63 (16065 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=12161 heads=255 sectors/track=63 (16065 blks/cyl) Media sector size

I sent this to freebsd-questions earlier via the newsgroup, but I just found out today that the list-to-news gateway has been down for half a month now. Any idea when it's going back up? Who was hosting that service anyway? And now for the question.. I have a test server that is being used to test a 4.4-REL to 4.8-STABLE upgrade, and I've found the system will no longer boot unless I

Hi, I would like to make a suggestion for a small syntactic modification of FUN argument in the family of functions [lsv]apply(). The idea is to allow one-liner expressions without typing "function(item) {...}" to surround them. The argument to the anonymous function is simply referred as ".". Let take an example. With this new feature, the following call

Hi, I am using levelplot, and would like remove from each panel (condition) its unused x levels. e.g. Remove from panel vs=1 the cyl level=8. data(mtcars) levelplot(mpg~factor(cyl)*factor(gear)|factor(vs)) Thanks for your help, Ronny -- View this message in context: http://r.789695.n4.nabble.com/Lattice-levelplot-remove-unused-levels-per-panel-tp4656087.html Sent from the R help mailing

I am trying to setup vinum on a box using 4.8 RELENG_4 (as of about a week ago snapshot). This box was running 4.6 /w vinum on same hard drives for the last 4 months wonderfully... but since it is my current 'scratch/backup' box, I just reinstalled with -STABLE. # uname -a FreeBSD polya.axista.com 4.8-STABLE FreeBSD 4.8-STABLE #22: Tue Jun 24 17:01:07 EDT 2003

Hi everyone, I just finished installing FreeBSD 6 RELEASE on my Toshiba Tecra A4 laptop and the installation was fine, however, when I rebooted the machine, I don't get the boot loader screen as if the machine can not see my drive! I tried the reinstalling and ensured that I set the slice to be bootable but that didn't change anything. Not sure if this is a common issue with FreeBSD 6 on

I'm sure this exists elsewhere, but, as a trade-off, could you achieve what you want with a separate helper function F(expr) that constructs the function you want to pass to [lsv]apply()? Something that would allow you to write: sapply(split(mtcars, mtcars$cyl), F(summary(lm(mpg ~ wt,.))$r.squared)) Such an F() function would apply elsewhere too. /Henrik On Thu, Apr 16, 2020 at 9:30 AM

Hi, I have lost a ZFS volume and I am hoping to get some help to recover the information ( a couple of months worth of work :( ). I have been using ZFS for more than 6 months on this project. Yesterday I ran a "zvol status" command, the system froze and rebooted. When it came back the discs where not available. See bellow the output of " zpool status", "format"

Hi everyone, I've run into a bit of strange problem with implicit vs explicit printing and the call stack. I've included an example at the bottom of this email. The basic problem is that I have an S3 object with a print method. When the object is implicitly printed (ie. typed directly into the console) the function arguments in the call stack are exploded out to their actual values,

Hi, I was trying to rebuild world on a FreeBSD 10 test system, that I had just installed. ZFS root was setup. I let the installation program do all the ZFS setup and configuration. I put root on a 5 disk encrypted raidz array. Besides the installer configuring 5 times the amount of swap space I asked for (asked for 8gb, installer put 8gb on each drive, for 40gb in total.) everything was working

Dear all ?Hmisc::rcorr states that it takes as main argument "a numeric matrix". But is it normal that it fails in such an ugly way on a data frame? (See below.) If the function didn't attempt any conversion to a matrix, I would have expected it to state that in the error message that it didn't accept 'data.frame' objects in its input. Also, I vaguely remember having used

Dear List I have math test scores for male and female students where gender is a dummy code (female =1). I also have a variety of other demographic variables. However to begin, I want to create a very simple stripchart where female math scores are a blue circle and male scores are a red triangle. I am having difficulty using conditional statements to accomplish this. Thank you. ------
