Hy all, I wish to use a variable as rownames for a set of datas. By example : > nom<-"toto" > prenom<-"tutu" > res<-c(1,2) > res<-t(res) > res [,1] [,2] [1,] 1 2 > colnames(res)<-c(nom,prenom) > res toto tutu [1,] 1 2 > nom [1] "toto" > I wish to call the rowname by the

Hy all, I need to draw something in 2 dimension that has 3 dimension, the choice has been made to use colors to display the third dimension into the graph. Has someone done something like that, i can't figure out how to parametize the colors. Thks for all ideas, COMTE Guillaume [[alternative HTML version deleted]]

Hi all, I have a Date, that has been converted to a number that represent the count of seconds since year 1970, how do i convert it to a date ? Example : >Limite_x<-c(1131408000,1163548800) >is(limite_x) [1] "numeric" "vector" But these numbers are dates, did R provide something that give you the date from this numeric vector ? Thks all. COMTE

Hello, I've got 2 dates like these : "2006-02-08 17:12:55" "2006-02-08 17:15:26" I wish to get the middle of these two date : "2006-02-08 17 :14 :10" Is there is a function in R to do that ? Thks all guillaume [[alternative HTML version deleted]]

Hy all, I'm plotting graphs using plot() function, they are on X axes POSIX dates: "POSIXt" "oldClass" "POSIXct" "POSIXlt" I can't figure out why sometimes it prints the month and days and sometimes it prints the unix timestamp. It appens usually when the xlim is short like only some days. xlim is settled as a POSIXt like this "2006-12-30

Hi all, I wish to draw 2 hist (or barplot) on the same graph. I can do it simply by using par(new=TRUE) , but it overlap with the first drawn, how to tell R to put in front of the graph the min value of the two graph in order for it to be seen and don't hide each other. I've been looking at help for barplot or hist but didn't find anything... (or my english is too poor to

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 don't suppose it's possible to create a pie chart in R? I've got 1500 some odd elements in a frame that are valued at either -1, 0 or 1 and I'd like to find a reasonable way to represent the distribution graphically...any ideas? Joshua Gramlich Piocon Technologies Chicago, IL

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

Hi all, I'm getting confused by date handling. I wish to read a date from a file wich is a number of seconds since 1970 (POSIXct). Then i wish to convert this date to a human readable form (POSIXlt) By example : ctDate<-1132963200 #"Wed Aug 30 14:24:37 2006" is(ctDate) [1] "numeric" "vector" ctDate isn't a numeric vector, it is a

Hey, i'd like to compose a clock-like looking plot composed out of two circles, each showing the length of a period (to compare them). first, to do so, it looked the easiest by using pie(), just puting multiple pie-charts over each other. the problem is that once the second pie is drawn, it replaces the first one. does anybody know how to add a second, smaller pie over an existing one,

Dear all, I'd like to produce a simple pie chart for a customer (I know it's bad but they insist), and I have some difficulties setting the initial angle. For example: pie(c(60, 40), init.angle=14) and pie(c(80, 20), init.angle=338) both present the slices in the same direction, where: pie(c(60, 40)) pie(c(80, 20)) present the slices in different directions. I read everything I

Dear all, After going through the Lattice doc and R-help list and google, I got the feeling that there is no function in lattice or other package to compute a pie chart object of class "trellis". Although pie charts are obviously not considered optimal even in the pie() doc ;-) , pie chart trellis objects would be easy positioned e.g. over a map drawn with the grids package. Can

Hi, despite the fact that pie charts often fail, I'll draw them anyway (in a case were they are not fail ;-) ). Does anybody know a package/methods which can draw pie of pie or bar of pie charts similar to that in MS Excel? -- Kind regards, Mathias

With a pie chart pie(c(11, 15, 16, 29, 31)) how can I generate labels for the chart, such as orange: 11 green: 15 blue: 16 red: 29 purple: 31 rather than the default labels that are drawn automatically 1 2 3 4 5 -- Mark Polishook, D.M.A. Technology Coordinator Morehead Hall, Rm 132 Center for Academic Advising and Adult Learning Montclair State University Montclair, NJ 07043 (973)-655-7114

Hi all, I am looking to create a pie chart from a given column in a .csv file. My class variables are as follows: entry_type, uniquekey, types, title, url, abstract, journal, author, month, year, howpublished So say I want to export a pie chart that groups together all entries under 'types' e.g. 3 x statistics 2x education etc. Im looking to have a piechart represent this

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

Hi , I am looking to making a panel of pie charts fo some of my dritribution data . I was wondering if there is a way in any R package to write a small script to do so. Thanks, Amin [[alternative HTML version deleted]]

I am having trouble finding out how to adjust the position of labels on pie charts. For the small wedges, many of the labels overlap making it impossible to read. Is there any way to offset the labels so that they don't overlap? Adam Green USGS Patuxent Wildlife Research Center [[alternative HTML version deleted]]
