Is there a cheat-sheet anywhere that describes how to do SQL-like manipulations on a data frame? My knowledge of R is rather limited. But from my experience it seems as though one can think of data frames as being similar to tables in a database: there are rows, columns, and values. Also, one can perform similar manipulations on a data frame as one can on a table. For example:

Dear All, I am having a bit of problem using the DBI and RMySQL package. I have already installed DBI but now I want to connect to MySQL. So how do I do it. The CRAN package repository does not have RMySQL windows binary to install from?

Is there a way to do text plots in R? I'd like to do some simple XY plots in R with the output in text (ascii). For example, with gnuplot I can do the following: echo 'set terminal dumb ; plot sin(x)' | gnuplot To generate a simple sin wave. Since I connect to a remote Linux machine using SSH, being able to generate a rough idea of what a plot will look like in text would be

Is there a way to stream data into R so that it can be used in a command pipe? Most Unix commands read data via standard input and read the script from the command line. For example: $ seq 1 10 | sed -e 's/^/foo /' $ seq 1 10 | awk '{print "foo " $1}' $ seq 1 10 | perl -lane 'print "foo $F[0]"' In contrast, R seems to read the script

Hello, I've the following list n: > n [[1]] [1] "NEW" "OLD" "PRG" [[2]] [1] "04h" "24h" [[3]] [1] "000mM" "010mM" "025mM" "050mM" "100mM" where n <- dimnames(some.multidim.array) I'm trying to define a generic function that generates meaningful names from this list, e.g.

Hello all, How can I increase/decrease the line length for screen wrapping? Currently when I run the following the output appears to wrap at just under 80 columns: > c(1:100) [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 [19] 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 [37] 37 38 39 40 41 42 43 44 45 46 47 48 49

Dear R-community, Using bwplot, how can I put the whiskers at percentile 5 and percentile 95, in place of the default position coef=1.5?? Using panel=panel.bwstrip, whiskerpos=0.05, from the package agsemisc gives satisfaction, but changes the appearance of my boxplot and works with an old version of R, what I don’t want, and I didn’t find the option in box.umbrella parameters Many thanks

Hi everybody, using bwplot for producing panel boxplot with 3 dimensions i want to add a mark on each boxplot representing one individual (on all its dimensions) till now, i didn't succeed getting the desired solution I want as well to keep the median symbols as a line Many thanks for your help christophe here is the tested code: ######################## library(lattice) ex <-

Does R have command or object name completion? R has several functions of modern shells built into it e.g. history mechanism, command-line editing, emacs key bindings. However, it doesn't seem to have command or object name completion. For example, in bash I can begin typing a command and then press the tab key to have the shell fill in the rest of the command (works for environment

Is there an IRC channel for R? I have a bunch of relatively simple questions that I can't find answers to. So it'd be nice to send them to an IRC channel rather than clutter up the mailing list. I'm sure after a few examples and pointers to the right docs I'll be able to find my way. Regards, - Robert

Hi Hal, > As we had briefly mentioned on IRC, one way of forming this 'stack', and its associated 'cnt' variable, is to use dynamic stack allocation. I hadn't really reached a decision on the mechanics yet. However, your suggestion while it can work within the current abilities of the IR, has the disadvantage that it is using an extra stack slot for the link pointer. I

Hi, The other day on IRC myself, Chandler, Hal and Pablo discussed recursive inlining. I've pondered a bit since then, and thought I'd get some background on the list with the aim of stimulating discussion. Our goal is to inline recursive functions. We have several workloads with recursive calls, and inlining them to a certain degree can improve performance by up to 30%. Inlining

Hello all, How does one enter multi-line content using ''puppet resource file ...'' at the command line? For example, I am trying to create a file called /tmp/hw.txt with two lines of content: $ cat /tmp/hw.txt hello world This does not work: $ puppet resource file hello_world \ path=/tmp/hw.txt \ ensure=file \ content="hello\nworld\n" This does, but use

Hi, Apologies for the very late response. We have manually tried the idea with a very simple Fibonacci sequence code. While being very very simple, the recursion cannot be handled by TRE. Because there are two recursive callsites, it also needs to keep some sort of state across iterations of the "while(stack not empty)" loop. We get between 2.5 and 8x slowdowns depending on which

Hi list, I don't know if somebody has spent a lot of time debugging strange problems with if else positioning - the parser seems to recognize only the syntax bellow - this is the only way of making these pieces of code to work. As far as i'm concerned, no examples were available (it would be so awesome to have them in the introductory manual!) #Try to change the placement of the
