Hi everyone, I'm very new to R and I like to learn a lot... actually I have a little problem concerning errorbars with xyplot. My data look like run target hemi x 1 1 Nichts Links 0.0007743240 2 2 Nichts Links -0.0008153365 3 1 Target Links -0.0015825950 4 2 Target Links 0.0088743785 5 1 Nichts Rechts 0.0015898995 6 2 Nichts Rechts -0.0011465190 7 1 Target Rechts -0.00222...

Here is my code, which plots three lines with errorbar. How could I add an extra line without errorbar to the plot? Thank you very much. beta.data <- data.frame ( method = rep(c("Wrong", "Correct", "Full Bayes"), each = T_obs), mean.beta = c(mean.beta1, mean.beta2, mean.beta3), t = rep(points, 3), std.beta = c(std.bet...

Hi, Does anyone know how i get rid of the marker point in my error bars? The bars default function (it seems) is to have a dot in the middle of the bar, however i don't want it there. I am using Hmis to draw my errorbars and code is a<-as.vector(tapply(Sporangia,list(Host,Isolate),mean)) b<-as.vector(tapply(Sporangia,list(Host,Isolate),sd)) c<-sqrt(b/36) errbar(c(1.5,2.5,3.5,5.5,6.5,7.5),(tapply(Sporangia,list(Host,Isolate),mean)),a+c,a-c,add=T) Cheers Anna [[alternative HTML version deleted]]

Dear all I have six variables of the average metal concentrations Var1 4.77 Var2 23.5 Var3 5.2 Var4 12.3 Var5 42.1 Var6 121.2 I want to plot them as a barplot with error bars. Could you help me? Cheers Maria [[alternative HTML version deleted]]

Hi Everyone, I would like to add errorbars to a lattice plot. I already have a function that adds error bars to a plot (originally written by George Gilchrist) which takes as arguments the coordinates of the point and then the size of the error bar. I would like to integrate it in my lattice code but I seem to be stumped. I can put the...

Hello, i use ggplot to plot some measures including CIs as horizontal errorbars. I get an error when the scale limits are narrower than the boundaries of the error bar and hence the CIs are not plotted. library(ggplot2) df <- data.frame(resp=c(1,2), k=c(1,2), se=c(1,2)) ggplot(df, aes(resp,y=k)) + geom_point() + geom_errorbarh(aes(xmax = resp + se, xmin = resp - se)) +...

I am having a problem creating a scatterplot with error bars using gplot. This is only my second day using R so I am very much a newbie. My x-values (OD600) are: 0.00400000 0.01866667 0.04733333 0.08733333 0.22466667 0.42400000 0.82066667 1.39233333 1.61100000 My y-values (cellconc) are: 2e+06 5e+06 1e+07 2e+07 5e+07 1e+08 2e+08 5e+08 1e+09 And my standard deviations (stdev) are: 0.001154701

Hi All, Can anyone show me how to add a error bar to my graphs. I am currently using this code g<-ggplot(means,aes(x=variable,y=value)) > g<-g+geom_bar(stat="identity")+facet_wrap(~Site+Season) > g Thanks, Akaalz [[alternative HTML version deleted]]

Hi, i'm using this lines of code: dodge <-position_dodge(width=0.9) ggplot(dfm,aes(x = X,y = value)) + geom_bar(aes(fill = variable), position=dodge, stat="identity") + geom_errorbar(aes(ymin=value-er, ymax=value+er),width=0.25, position=dodge,stat="identity") to plot this data frame X variable value er 1 A X4 58.74 9.44 2 B X4 52.41 10.01 3 C X4 95.52 4.88 4 A X1 75.51 8.54 5 B X1 0.73 23.20 6 C X1 96.66...

Dear R-list I'm working with with geom_errorbar; specifically I'm trying to reproduce the example Hadley Wickham have on http://had.co.nz/ggplot2/geom_errorbar.html (all in the button of the page) where he makes an nice plot with errorbars and then draw lines between the points. What confuses me is the 'limits' he defines for the er...

Hi! Could you tell me how I can draw a graph with error bars? Sorry, I don't use R that often and I couldn't find it easily in the documentation.

...I later want to plot the data using barchart eg (barchart(date ~ mean | dataset, data=testdata);) in which case will the dates appear in assending order of dates or something special needs to be done for that. 3. Also I'll really appreciate if anyone can tell me if there's a way to get stdErrorBars on charts that are drawn using barchart function in lattice package. Any help or advise is greatly appreciated... Thanks, Sandeep. [[alternative HTML version deleted]]

Hi there,? I've been battling with an extension of this in my own data: getting appropriate error bars once data is stacked in a bar graph.? (original question: http://r.789695.n4.nabble.com/ggplot2-se-variable-in-geom-errorbar-s-limits- td3311176.html). It wouldn't let me reply to that thread. A modification of the earlier answer:? data(diamonds)? ?diamonds_df <- ddply(diamonds, .(cut, color), summarise,? ? ? ? ? ? ? ? ? ? ? ? ? mean_price = mean(price),? ? ? ? ? ? ? ? ? ? ? ? ? se_price = sd(price)/sqrt(length(...

Dear R-help members, I have several large data sets from certain simulations I did and now I want to plot the results nicely. I don't know anything about the size of the x and y values in advance. Plotting these values is not a problem. However, I want to add errorbars (errbar in the Hmisc package). 1) For this I'm factoring the data (xdata00 varies from 0 to max(xdata00)) xfactor00 = factor(cut(xdata00, breaks = (max(xdata00)/10)*(0:100))) 2) I compute the means of the different levels ymeans00 = tapply(ydata00, xfactor00, mean) 3) I compute the errors...

I'm trying to compare the results of several models using output from bugs(). I want to summarize the models via boxplots or lineplots of the parameters. I know how to use errorbars from a regression, but how do I implement the credible intervals as error bars into these plots Any help is much appreciated Matthew Krachey [[alternative HTML version deleted]]

...ere, Using the code below I generated the plot attached. The error bars at day = -3, 2 and 4 appear are larger. I was thinking if there is a way I could make all the error bars to be of the same size. I don't know if that makes sense. If not, then, is there a way I can plot only these 3 largest errorbars at day axis (day = -3, 2 and 4) and omit the rest of the error bars. I would be much obliged for any help Warmest Ogbos temp<-split(y,x) means<-sapply(temp,mean) stderr<-function(x)sqrt(var(x)/length(x)) p<-sapply(temp,stderr) n<-sapply(temp,length) ciw<-qt(0.975,n)*p/sqrt(n...

Hi, I'm having problems using the 'width' aesthetic attribute for the geom_errorbarh. This is the same problem reported earlier here, but I'll try to write the problem more clearly: http://www.mail-archive.com/r-help@r-project.org/msg62371.html The problem I'm having is that, the 'width' attribute is supposed to set the height of the endpoints of the whiskers,...

I want to obtain a barplot with error bars and a mean plot with error bars with other scale on the left in the same plot. I need help to get the same x axis (centered) when overlay two plots (barplot2 and plotCI (or lineplot.CI) with errorbars), with diferent y axis. I use par (new=T) but the X axis names are not centered with the figures. An example of my data: mean1<-cbind(55.5,56.42,56.38,55.28) SD1<-cbind(10,9 ,7 ,3) x<-rbind(mean1,SD1) colnames(x)<-c("Autumn","Spring","Summer",&quot...
