Dear all, This seems like a simple problem but i've searched the help files and tried various options but failed, so apologies in advance for asking what i'm sure is an easy thing to do! In short, I have displayed behavioural data using the TraMineR package such that there is a colour change between the transition of behaviours, however, all the methods that i have used thus far have

#I would like to interpolate a straight line between 06/08/06 04:16:00 - 06/08/06 20:31:00 with values and then sum them. This is an estimate of ecosystem #respiration and I will be using this in a larger context(48 days of these diurnal curves), but for right now I am just trying to figure out how to do it for this one #day example. I have some other code for Ecosystem (stream) Metabolism that

Dear All- I am trying to create a legend where the first 9 terms are represented as pch=16 in one column (which I am able to do); but, I would like the last two terms in that column to be 'lines" (which are black and red - just as it looks like in the plot). I have read through many help pages and searched the help listserv, but haven't figured this one out yet. Does anyone have

I frequently work with hourly data in GMT format, and ensure that any data I read into R are expressed in GMT through as.POSIXct(mydate, tz = "GMT"). I am interested in processing air pollution data in GMT where where peaks in emissions (say from road traffic sources) tend to occur at the same LOCAL time each day. I am interested in calculating mean concentrations by hour of day i.e.

Hi all, I'm announcing this version of plotrix because I have made a couple of changes that will affect users. Although the function that used to be known as hierobarp is fairly new, there may be some users who are surprised when they find that it has changed its name to barNest. I will probably rename the two functions hierobarp.svymean and hierobarp.svyprop in the next version to

I have been trying to visualize times of lowest tides, month by month. I have tide predictions with times either in unix time or a text format, and heights in feet or meters. I had been able to derive the clock times of each prediction. I would now like to graph this data with points showing heights as "r" and times as "theta", from 0000 to 2355. There is a seasonal

Dear R Users, If a variable, say CO2(ppm), is varying with time. Then how to calculate CO2 (ppm) growth rate /a-1 I have CO2 time series (1991-2000), as: time, year, month, day, hour, min, sec, lat, long, height, CO2 1991.476722 1991 6 24 0 5 0 -38.93 145.15 4270 353.680 1991.476741 1991 6 24 0 15 0 -39.20 145.22 4270 353.950 1991.476747 1991 6 24 0 18 0 -39.43 145.28 4270 353.510

I want to plot quantitative data as a function of three two-level factors. How do I group the bars on a barplot by level through labeling and spacing? Here <http://www.thomaslevine.org/sample_multiple-factor_barplot.png>'s what I'm thinking of. Also, I'm pretty sure that I want a barplot, but there may be something better.

Hi, I have a data set with two continous variables that I want to plot MEANS (I am not intrerested in median values) on a double-y graph. I also have 2 factors. I want the factor combinations plotted in different panes. Dummy dataset: mydata <- data.frame(factor1 = factor(rep(LETTERS[1:3], each = 40)), factor2 = factor(rep(c(1:4), each = 10)), y1 =

Hi all, I am struggling to work out how to use the rownames from an edited dataframe rather than the row names from the original dataframe. In my data set i'm trying to extract several rows of data on particular individuals, i don't doubt i'm using the long way round but what i have in the way of a script is this: ##selecting the IDs from the dataframe individually

Hello. I need to plot a two-way interaction (5 levels X 3) with error bars. The x.factor will be the five-levels var and the trace.factor will be the three level var. I was able to find functions that draw error bars, but still couldn't find a way to draw an interaction plot that looks like what is common in psychological (and related) journals: the lines (three in my need) are plotted in

Dear R users, I have 32 observations in data x. After sorting this, I want to compute means and variances of 3 groups divided by "nr". Actually, the number of groups is flexible. Any suggestion will be greatly appreciated. Kathryn Lord --------------------------------------------------------------------------- x=rnorm(32) y=sort(x) nr=matrix(c(12,11,10,10,10,11),2,3) > nr

Dear useRs, I can't seem to find out how to categorize my histogram. I have the following dataset: Time??????????? First.day?

Hello fellow R users, I have an issue that has me a little confused - sorry if the subject makes little sense, I wasn't sure how to refer to this problem. I have a data set I've extracted from ArcInfo (a section is shown below). It is spatial data, showing the distance from one ID to another. I want to get the actual 'TO' ID from the data set (there is no easy way to do this in

Hi everyone I''m Maximiliano Guzenski from Brazil and I am programing on ruby on rails only a couple of months. I read a lot of books and articles about it but I could not clarify some doubts about design patterns: 1) Is it really good put some sql command on controller? because all articles that I see use sql into controllers, like: # my controller @categories = Category.find

If the software licensed to run only on Machine X and Machine X has now been junked and replace by Machine Y, then isn't the

Sorry if you have had this problem many times before. I just can''t seem to find the problem.
