similar to: problem with axis alignment when plotting 2 time series on same graph

I have a time series of about 1500 measurements. There are sporadic data gaps. I would like to plot the time series with type "line". I only want a line to connect the periods with data; I don't want a line to connect the points across a data gap. Is there a function or recommended method to deal with this? For example there are 2000 days days 1:1000 each have one

I have a simple barplot of 4 mean values, each mean value has an associated 95% confidence interval drawn on the plot as an error bar. I want to make a legend on the plot that uses the error bar symbol, and explains "95% C.I." How do I show the error bar symbol in the legend? I could not find any "pch" values that are appropriate Thanks [[alternative HTML version

I have read the R manual and help archives, sorry but I'm still stuck. How would I do a t-test with an adjusted p-value? Suppose that I use t.test ( ) , with the function argument alternative = "two.sided", and data such that degrees of freedom = 20. The function calculates a t-statistic of 2.086, and p-value =0.05 How do I then adjust the p-value? My thought is to do

Hello, I would like to suggest the following change to image.default in src\library\graphics\R\image.R: 98c98 < plot(NA, NA, xlim = xlim, ylim = ylim, type = "n", xaxs = xaxs, --- > plot(x[1], y[1], xlim = xlim, ylim = ylim, type = "n", xaxs = xaxs, This provides all the support of axis.POSIXt that plot.default gives, currently the default new plot in

About a week ago, XL Solutions Corporation posted to this list with a solicitation for course offerings in R. I looked at their site, and many courses do look interesting. Can anyone provide feedback on the quality of their courses? [[alternative HTML version deleted]]

I have a matrix with 12 rows (one for each month), 2 columns (baseflow, runoff). I would like to make a barplot similar to Excel’s “clustered column chart”. Here is my matrix ‘x’ 8.258754 13.300710 10.180953 10.760465 11.012184 13.954887 10.910870 13.839839 9.023519 11.511129 7.189241 12.519830 5.925576 17.101491 5.211613 13.585175

Hi there! Both on windows and Solaris platforms I run into troubles when trying to draw two plots on top of each other. Here a short code example: > x1 <- c(2,3,4,5,6,7,8) > y1 <- sin(x1) > x2 <- c(1,2,3,4,5,6,7,8,9,10) > y2 <- cos(x2) > d1 <- cbind(x1,y1) > d2 <- cbind(x2,y2) > plot(d1) > par(new=T, xaxs="d") > plot(d2) Error in plot.new()

Hi,   I would like to distinguish my plots using colors but I got error message.  How do I correct that?     plot(ecdf(z), main ="CDF for observed and simulated weighted sum",type="l",lwd=2,col="blue", xlab="Weighted sum (mm)", ylab="Cumulative Percent", xlim=c(0,15), xaxs ='i', yaxs ='i',ylim=c(0,1)) par(new=TRUE)

I have a time series with interval of 2.5 minutes, or 24 observations per hour. I am trying to find a 1 hr moving average, looking backward, so that moving average at n = mean(n-23 : n) The time series has about 1.5 million rows, with occasional gaps due to poor data quality. I only want to take a 1 hour moving average for those periods that are complete, i.e. have 24 observations in the

Dear R Users, I am a beginner in R programming and need some help with a simple plotting problem that i am having. My dataset consist of three columns: first one has data_id, second is the date and third is the actual data itself corresponding to each date. The date ranges from 1/1/2000-12/31/2009. I am trying to plot my data versus the dates as a long term time series but

Hi, I am using the following code as an example function to create multiple y-axes on one plot. I have it working fine however, I can't seem to add a label on the second (right) axis. I have tried adding ylab="y2" in the axis call but, that didn't work; any ideas? Thanks, Jesse Code: function() { par(las=1,xaxs="r",mai=c(1,0.75,1,1)) x<-1:10 y1<-x

This seems like a simple thing, but I have been stuck for some time. My data has 2 columns. Column 1 is the value, and column 2 is the Site where data was collected. Column 2 contains 7 different Sites (i.e. groups). I am only interested in showing 3 groups on a single boxplot. I have tried various methods of subsetting the data, in order to only have the 3 groups in my subset. However

hi, i am using par(mrow=c(6,6)) function to get 6x6 plots on one screen. the problem that i am having is that the axis tick labels are far away from the ticks and going into previous plots (see attached figure). i need to know how can i reduce the distance between the ticks and their values (y axis values).the part of the code that i am using (after reading in the data) to create the top row is:

Hi everyone I want a square scatterplot with abline(0,1) going exactly through the SW and NE corners. By "square" I mean that the plotting region is exactly square, and that the axis limits are identical. x <- 1:20 y <- x+rep(c(-1,1),10) lims <- range(c(x,y)) None of the following do this: plot(x,y) ; abline(0,1) #not square plot(x,y,asp=1);abline(0,1) #diagonal

Full_Name: Mark Wall Version: 1.6.0 OS: linux Submission from: (NULL) (63.251.119.254) I want to plot a histogram of a *subset* of some data: >t = c(0:9) >hist(t,right=FALSE,breaks=10,xlim=c(0,5),xaxs="i") This means I should plot a histogram from 0 to 5 with breaks at 1,2,3,4. This should produce exactly 5 bars of frequency=1. Instead I get 5 and 1/4 bars. I do not want the

I ran into a weird, to me at least, problem, and hoping someone can shed some light into it. In a nutshell, there seems to be some problem when one calls plot with a formula, from within another function, using ... to pass arguments, and one of those arguments being xlim (and only xlim shows this problem). Here is an example: > plotw <- function(obj,...) { + plot(k~j,

Dear R community, I need to plot the results of some simulations I did using QTL Cartographer. I am plotting LOD scores over three chromosomes. The three plot have to be one next to the other. The procedure I am using is: par(mfrow=c(1,3)) plot(x$x, x$y, ylim=c(0,35), type="l", col="blue", las=1, xaxs="i", yaxs="i", xlab="X Chromosome",

Dear R users, The parameters xaxs and yaxs (function par, package graphics) seem not to work with the function hist (package graphics), even when the parameters xlim and ylim are defined. Is there any way to make yaxs="i" and xaxs="i" work properly with the function hist, mainly to produce histograms that "touch" the horizontal axis? The R documentation and the R
