similar to: Plot several graphs in the same window

Hello! I would like to make a scatterplot of my data, but the problem is that several points have the same x and y values and are represented as only one point. I wonder if there is a way to represent the data points, but with point size representing the frequency of the depicted x-y value? Thank you! -- View this message in context:

Hello! It is not really linked to R, but can somebody explain me why we sometimes make a mantel test directly for to distance matrices and sometimes we first make a gradient analysis and then a mantel test between the axis?

Hello, I plot the abundance of a species in relation to the date. To have the date as a continous variable I put it in the format "standard" in excel (f.ex. 39939 means 06.05.2009). R uses 39939 on the x axis, but I would like to have "06.05". I tried to use as.Date as suggested in some discussion but I don't manage to use it, the returned date is not correct. Do you have

Hello, I performed a Mantel test and plotted communitiy similarities. I would like to add a least square line. I thought about using abline taking as slope the r-statistic of the Mantel test and calculating the y-intercept analytically. Is this method correct? Is there any function for this calculation?

Hello, I am trying to do contrasts after applying a binomial mixed effect model with the function lmer. I have to extract the fix effect values, but as I write fixef(model), I get this error message: Error in UseMethod("fixef") : no method for 'fixef' with objects of class "mer" Has anybody some ideas why? And how can I then post-hoc testing my data if I cannot do

Hello! I am trying to model data on species abundance (count data) with a poisson error distribution. I have a fixed and a random variables and thus needs a mixed model. I strongly doubt that my model is overdispersed but I don't know how to get the overdispersion parameter in a mixed model. Maybe someone can help me on this point. Secondly, it seems that quasi models cannot be implemented

Dear All, I am sorry if this question has been asked before. Below is my Question: I want to put several plots in the same window, but I don?t want the blank space between plots (like par(mfrow=)) --- that makes the plots too small. Could anyone tell me how to do it? Thanks a lot. Frank

Hi all, I have a basic question concerning graphs in R. I?m using the par() function and I?m working with multiple figures by row (mfrow) but my the hight of my figures become compressed. I have 4 rows and 2 columns (because I want to plot 8 histograms (freq = FALSE ) on it. I know I can adapt my margins with for example ?oma? and ?mai? but I don?t know how to choose the size of the figure? I

Hi, I am trying to generate a figure of 9 plots that are contained in one device by using par(mfrow = c(3,3,)) I would like to have 1 common legend for all 9 plots somewhere outside of the plotting area (as opposed to one legend inside each of the 9 plots, which the function legend() seems to generate by default). Any hint how to do this? Best, Georg

Hi, I want to draw several pictures on one plot and do as follows: xy<-matrix(rnorm(100,100,10),50) op <- par(mfrow = c(2, 2), pty = "s") plot(xy,ann=F);plot(xy,ann=F);plot(xy,ann=F);plot(xy,ann=F) par(op) What I need now is to set the size of the pictures within this plot since there is too much free space among the pictures, making the plot look not that pretty. How can I do

Hello! I want to display four xyplots in the same window (sorry if I don't use the propers words, but my English is rude) I know that if I use plot(y~x) then x=(1:100) y=(1:100) par(mfrow=c(2,2)) plot(y~x) plot(y~x) plot(y~x) plot(y~x) would give what I want, but this is not the case because I need the functions of xyplot. So I did the following: plot.new()

Dear R-help list: I have want seems to be a simple task, but can't find a solution. I tried querying the archives, but did not succeed. My goal is to set up two (or more) graphs in one graph window, and then during execution of a sequential algorithm add points sequentially to these graphs. The graphs have different scales / coordinates. I use the par(mfg...) command to switch between

hello - a question about filled.contour plots, for which i haven't found a response in previous posts - sorry if already treated. i'd like to draw several filled.contour plots (that is, maps) on the same device (a postscript file, actually). I know about layout(matrix) , split.screen or par(mfrow) : it works well for simple plots, but with filled.contour plots, i get several pages

Dear R people, I am using par(mfrow=c()) to plot multi-figures in the same window. And I like to put a common title (and xlab, ylab) for all of plots. I have already left some margin by resetting omi values in par() and hided all (xlab, ylab) for each sub-plot. Could anyone tell me how to do that? Thanks a lot, Frank

I have the following codes but can anyone make it shorter i.e making these FOR loop into one loop ... thanks... par(mfrow=c(2,4)) for(i in 16:23){ hist(data[,i],main=paste(colnames(data)[i],sep=""),ylab="Frequency",xlim=c(1,5),xlab="Score",ylim=c(0,100)) } png("histogram.png") dev.off() par(mfrow=c(2,4)) for(i in

I am new to R and have a problem that I haven't been able to find the answer to in the guides or online. I have multiple datasets, D1, D2, D3, D4, D5, D6, D7 and D8, and I would like to produce two plots side by side using mfrow.  The first plot should contain data from D1-D4, the second should contain D5-D8. I can plot these separately using the code, par(mfrow=c(1,1))

Hello! I have a dataset with monthly temperatures for 4 different years and I would like to test if they are significantly different between the years. As I collected the data for different sites I wondered if there were some possibility to perform the calculation at once or if I have to repeat it for each site. I tried like this: Model_Temp <- lmer(Temp ~Year +

Hi, I am struggling to create a 2 by 2 multiple graphs in one page. I used par(mfrow=c(2,2)) to divide the screen into 4. In each screen I draw a pie chart (They are all same). For example, my data is like this Concentration value A1 69 A2 8 G1 51 G2 1

Dear Users, I already posted this question: it either went unnoticed, or it is to basic (if this is so, please sent me a hint). I would like to know if there is a way to add a common legend to an arrangement of plots. In the example below, I get four plots in my device. each one has a density for 1995 and one for 2006. I have found that using legend or smartlegend I can add a legend to each plot,
