I hope that somebody can help me with this - I think very simple - issue...? I am running a package that only accepts one line at a time, but I would like to run this package on a dataframe of >500 lines. Dataframe "d" is a single column: APPLES PEARS AUBERGINES KUMQUATS I would like to read one line of my dataframe "d", individually into a new frame "f", then

This may be a simple problem, but I am looking to select a subset of rows from a dataframe that will have the same parameters as all the rows in another dataframe. e.g. I have a 500 row dataframe with 20 columns. I want to select a subset of rows from a larger dataframe that match the distribution of values for one or more of the columns within the 500 row dataframe (i.e. within same range, but

I have a list. my.list <- list(Tom=c(1,2,3), Dick=c(4,5,6), Harry=c(7,8,9)) I assign one of the names of the list to a variable. name <- "Harry" I can access the value of the list using the variable as follows: eval(parse(text=paste("my.list$", name, sep=""))) [1] 7 8 9 But how do I change the value of my.list$Harry using the variable name? This

I've looked long and hard for this, but maybe I am missing something... There is a nice module that displays histograms reflected in the y axis, i.e. http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=136 but is it possible to reflect in the x-axis, so to have two datasets, one pointing up and one down rather than left and right? I haven't been able to find a way to plot this

Hi R-Helpers, Sorry to bother you, but I have a simple task that I can't figure out how to do. For example, I have some names in two columns NamesWide<-data.frame(Name1=c("Tom","Dick"),Name2=c("Larry","Curly")) and I simply want to get a single column

Just to repeat: you have NamesWide<-data.frame(Name1=c("Tom","Dick"),Name2=c("Larry","Curly")) and you want NamesLong<-data.frame(Names=c("Tom","Dick","Larry","Curly")) There must be something I am missing, because NamesLong <- data.frame(Names = c(NamesWide$Name1, NamesWide$Name2)) appears to

Hi, You were on the right track using stack(), but you just pass the entire data frame as a single object, not the separate columns: > stack(NamesWide) ? values ? ind 1 ? ?Tom Name1 2 ? Dick Name1 3 ?Larry Name2 4 ?Curly Name2 Note that stack also returns the index (second column of 'ind' values), which tells you which column in the source data frame the stacked values originated

I just put a USB hard drive into service, but find that unless the drive is connected to my PC the machine won't boot and drops to a shell. Below is the line I added to fstab. I thought that the option "noauto" would prevent the machine from trying to mount the drive /dev/sdb /usbdrive ext3 user,noauto,rw 0 2 What am I doing wrong? Any advice is

I may be missing something but using the plain old c() combine function seems to work fine: df <- data.frame(left = 1:5, right = 6:10) df.combined <- data.frame(comb = c(df$left, df$right)) df left right 1 1 6 2 2 7 3 3 8 4 4 9 5 5 10 df.combined comb 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 10 10 -----Original

Hi everybody I am trying to get RoR to work with lighttpd. Nearly there, but I am stuck with a strange phenomenon. If I configure lighttpd to serve pages on say port 2000, I can get at my testapp fine and see the "Welcome aboard" page. However, if I configure lighttpd to use port 80, I get a download prompt from my browser. If I access my URI like

I'm looking into backing up my CentOS 5.5 system using an external USB 2.0 hard drive. Anyone with experience with Toshiba Canvio USB 750 GB unit? I'm backing up to DVDs now and would like to streamline the process. Any advice is welcome with thanks. Dick -- Yes indeed...the Hokey Pokey *is* what its all about!

scrub completed after 1h9m with 0 errors on Tue Feb 17 12:09:31 2009 This is about twice as slow as the same srub on a solaris 10 box with a mirrored zfs root pool. Has scrub become that much slower?

I am receiving this error running a command on a multi-row data-frame. The data is strings of text (each with new line separator, no spaces, no numerical characters). Error in FUN(X[[1L]], ...) : STRING_ELT() can only be applied to a 'character vector', not a 'integer' I can run single text string into the same command, and so the issue seems to be how the package deals with the

Good Morning-- I'm looking to shore up security in my system and with communications. Can you point me to the proper version of GnuPG for CentOS 5.3 (Final)?

I'm using Simplecast to feed 8 mount points of a 24/7 live stream to Icecast on a win platform. When I have the Statistics Relays graphing activated, I get an entry each minute in Access.log for each of the mount points. That particular entry is pretty much useless but of course, being able to see the IP address of client drops can be useful. This log grows to mammoth proportions unless I

After a liveupgrade and luactivate I can login to the -new- BE. My question is: do I have to luactive the -old- BE again if I want to chose that one from the grub menu or can I just run it if I want to. -- Dick Hoogendijk -- PGP/GnuPG key: 01D2433D + http://nagual.nl/ | SunOS sxce snv107 ++ + All that''s really worth doing is what we do for others (Lewis Carrol)

Greetings I'm new to the forum but have been streaming successfully with SimpleCast/IceCast2 for about 8 months. Both Simplecast and IceCast2 are running on the same Win2K system. Now I want to do something that has me stumped. It really is a two pronged problem. Here's the setup: Icecast is encoding the same live audio to multiple mount points, allowing me to easily track the
