I am trying to plot 2 time series on the same graph. For example, X1 is the vector of dates and times, its class is POSIXt. Y1 is an environmental parameter, e.g. salinity. X2 is a second vector of dates and times, also of class POSIXt. X2 has a different length than X1, but they have the exact same range. Y2 is another environmental parameter, e.g. stream flow rate. My approach is

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

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 All, I have a question on overlaying a filled.contour (e.g. on soil properties data) and contour (by elevation) in one graph. Both have the same z matrix dimension. I'm able to overlay both graph, but the plots dimension did not overlap well on the same plots. How can I have both filled.contour and contour on the same graph? The commands that I have written are as follows:

Hello: I have done this before but cannot figure out how to do it again. I would like to graph campaign evolution of news stories on certain topics. The campaign time period is as follows: campaign<-seq.Date(from=as.Date('2011-09-06'), to=as.Date('2011-10-5'), by=1) I have a table of newspaper story frequencies containing a certain word that can be turned into a data.frame

I am new to R and am trying to solve the following problem: I have a data file containing tick-by-tick, millisecond level prices for some stocks. I have another file or two containing orders and trades, again, with millisecond time-stamps. Both of these files are irregularly spaced and the time stamps are in an iso format (<date> <time>.<millisecond>) I would like to create a

R 2.10 Windows 7 I am trying to plot three graphs on top of each other. I need to have the axises perfectly aligned. For some reason the ticks on the y axes are slightly off so they do not perfectly align. Can someone tell me how I can get the to overlay each other perfectly? I thought the yaxp parameter would solve my problem, but it does not. My data and code follows: >

Hello, I have four different time series from the same time period within a year (February through August) but they are from different years. I can not figure out how to plot them all (so they will be overlayed instead of plotted on after another) on the same graph with the x-axis corresponding to the month/day instead of year/month/day. Thank you. Max

I saw in the archive a post from Mark Wilkinson (Feb 1, 2003), saying that some of his R-generated png plots came out overlapping. I am seeing the same thing (with R 1.6.2 on Linux i686). My input file generated 4 plot files. The first two were fine, but the last 2 featured a weird overlay of the remaining graphs. The problem is not seen with postscript of pdf output. -- Allin Cottrell

I have searched the forums but I am having trouble trying accomplish two specific plots. I am not sure if this is a very basic task but I am having a lot of trouble Here is my data frame: date prod_daily price 1 2003-08-15 12050 4.83 2 2003-08-18 12050 4.94 3 2004-08-10 12300 5.78 4 2004-08-11 12300 5.64 5 2004-08-12 12300

Hi there, I need to merge/bind two time series objects (from RPackage: timeSeries) by column. The theory is laid out nicely, even for overlapping indices. In my example, I have overlapping indices ("01.01.2001"), where in one time series I have one data point and in the other redundant data. Default usage of merge and cbind would lead to the result that the one data point would be

hi, There are two types of plotting I miss dearly in Matlab, can anyone enlighten me how to do similar stuff in R? - multiple figures with individual windows (not multiple figures in same window)? - draw something, hold on the drawing, wait for a key action, then overlay on top? Not sure if this makes sense, just want to check if there are developed techniques for them. Thanks Oliver

So I've got a 154 column wide xts time series object and I want to plot the 154 series on a single plot and have the added benefit of the time series dates on the x axis. Any suggestions for plotting functions, maplot works but does not give dates on the axis and I can't seem to get plot to give me more than one series. Nick [[alternative HTML version deleted]]

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

I am trying to plot two 3-dimensional time series in one window (such that there will be 3 rows and 2 columns). For zoo and ts objects the par(mfrow...) option does not work. I can get xyplot to make the plots, but data are on widely different scales in the three dimensions, and xyplot uses the same scale on all y-axis which means that in some dimensions the curves will be almost horizontal lines.

Dear all, I have a data set containing GPS fixes of animal locations. To check that the GPS's are working properly, I would like to plot the time of the fixes (y-axis) against the date of the fixes (x-axis). If all works well, the plot should show four regular fixes per day. The x-axis should be labelled with month/year (i.e. 11/04) and the y-axis by hour from 00 to 24. I would like to

Hi there, when plotting a time series I got this error message: Error in xy.coords(x, y, xlabel, ylabel, log) : x and y lengths differ In addition: Warning messages: 1: longer object length is not a multiple of shorter object length in: vx.1[int.lr] + (-1) * vx.2[int.rl] vx.1[int.rl] and vx.2[int.rl] have the same length. Does anybody know what the warning message means? Thanks, Sven
