Can a single random number be generated in R? I have an exercise that wants to simulate coin tosses, and I cannot seem to find a good example of the use of random number generation in R. Any help? Joshua Gramlich Chicago, IL

Is there a way to edit user defined functions once they've been created? For instance, I've a simple function that plots a table, but I'd like to go back and add more parameters to the barplot call. Is there a way to change this function without completely starting from scratch? Other than storing the code in a file and re-running it? Joshua Gramlich Piocon Technologies Chicago,

Hello, My questions are meant to be not necessarily specific...I am looking for advice and best practices for setting up an R environment. Here's my situation: I am one of perhaps three or four individuals who will be analyzing the same data through the use of R. I would like to set up a "base" environment for our project, basically some scripts that connect to a database, load

I think this may be a histogram, but I'm not sure. Can anyone tell me how to replicate this graph in R? http://www.ginworks.com/images/multitot.gif Thanks, Joshua Gramlich

Have you read the books by Cleveland? His experiments show that most people do better estimating things and comparing things on a linear scale rather than looking at angles and areas (also see http://biostat.mc.vanderbilt.edu/twiki/pub/Main/StatGraphCourse/graphsco urse.pdf) With a dot chart you can set the axis to go from 0 to the total of all groups (see the example I sent before, it could

I have only just discovered the joys of the dotchart (since I am reading William Cleveland's -- Sean Carmody The Stubborn Mule http://www.stubbornmule.net http://twitter.com/seancarmody [[alternative HTML version deleted]]

Is anyone using R with postgres? I'd like to do so, but cannot seem to find any reasonable explanation of how to do so. Joshua Gramlich Chicago, IL

Hi list, I'm using barplot2 form the gplots package to plot a few numbers (I want to add SD bars later). However, I would like the y-axis not to start from 0 but 500. When I add the parameters YLIM, something goes wrong. The graph is not 'cut off' at 500. Instead the bars seems to sink trough the bottom of the graph. Because its a little hard to explain, here is a self-containing

Hi all, Is there a way to draw 3D pie with R (like excel does)? I know how to do it in 2D, just by using pie(something)... I know it isn't the best way to represent data, but people are sometimes more interested by the look and feel than by the accuracy of the results... If there is no way, have you another suggestion ? (i already use dotchart instead of pie) Thks to all of

Hi, My problem is: I have many data to plot as pie-chart, so the labels are not readable! Is there a way to solve my problem? For example is it possible move the labels more far to the graphic? Thanks in advance Marco

Hi, I would like to draw a pie chart. I've already tried out the standard pie-function in the GRAPH-package. My question: is there any 'better' function or package to draw a pie chart. For example I would like to draw a 3D pie chart. Dietrich Tissen

I am new to R. I want to graph group data using a "Traditional Bar Chart with Standard Error Bar", like the kind shown here: http://samiam.colorado.edu/~mcclella/ftep/twoGroups/twoGroupGraphs.html Is there a simple way to do this? So far, I have only figured out how to plot the bars using barplot. testdata <- scan(, list(group=0,xbar=0,se=0)) 400 0.36038 0.02154 200 0.35927

I have some data which I would like to display with dotchart. The labels are very long, so the chart becomes too small. Setting cex=0.7 seems to be a good compromise, but the gap between the text and the chart still is too large. I did not find a "gap" parameter in the description of dotchart... Thanks for any help. D. Trenkler "a" <- structure(c(103.35, 36.73, 55.09,

Running R 1.8.1 on a Windows machine In dotchart, I would like to shrink the labels on the tick marks (that is, the numbers) without shrinking anything else. I could not find this in either the Rhelp archives or in ?dotchart, which recmmends cex to avoid 'label overlap', but cex shrinks all the characters in the plot. Is there a way to do this? Thanks Peter Peter L. Flom, PhD

I am trying to put 3 dotcharts side-by-side with minimal space between each. Each chart is for a different variable, but the vertical axes are the same. I want to have vertical axis labels on the lefthand chart but no vertical axis labels on the other two. Plus, I would like very little space between charts 1 & 2 and between charts 2 & 3. I have one approach but am not too happy with

I have a factor vector of subject races (Asian, Black, Hispanic, White; n=30) that I want to plot with a Cleveland dotplot or dotchart. I tried the following in R2.12.1 : > dotchart(table(school$Race)) Error in plot.xy(xy.coords(x, y), type = type, ...) : invalid plot type Using the same data set in R2.11.1 the operation succeeded (I tried several variations to be sure): >

One quirk to be watched is the use of connections to the DBMS via the Unix sockets vs ports. The PostgreSQL driver bundled with unixODBC will use Unix sockets to `localhost', but this driver seems unreliable (see the ChangeLog). The current driver will only use a TCP/IP port, and to use that needs postmaster started with the -i flag (which is not the default) and with tcp/ip

We regularly get questions about making pie charts, and frequently veer off into the philosophical and practical issues surrounding that form of data graphic: human perception of angles and so on. So while this isn't an R issue, I thought some of you might appreciate this brief discussion of the efficacy of pie charts: http://fakescience.tumblr.com/post/6042293374/understanding-pie-charts
