Hi all, I have two datasets, one that represents a long-term time series and one that represents summary data for the time series. It looks something like this: x<-data.frame(Year=c(2001,2001,2001,2001,2001,2001,2002,2002,2002,2002,2002,2002), Month=c(1,1,1,2,2,2),Q=c(5,5,5,6,6,6,3,3,3,4,4,5)) y<-data.frame(Year=c(2001,2001,2002,2002),Month=c(1,2,1,2),Threshold_Q=c(5,5,4,4)) What I'd

Hi all, I'm trying to identify a particular digit or value within a vector of factors. Specifically, this is environmental data where in some cases the minimum value reported is "<" a particular number (and I want to manipulate only these). For example: x<-c("1","2","3","4","<1") For a dataset that is hundreds or

Hello, I'm attempting to write a code that automatically imports data from different files (with different lengths-just one variable) and makes tidy box plots for comparison. I can successfully import the data and create a list of the vectors I want to compare. But I cannot, for the life of me, figure out how to generate box plots using the "list" option. Suppose these are my data:

Hi R-users, I'm trying to find an elegant way to count the number of rows in a dataframe with a unique combination of 2 values in the dataframe. My data is specifically one column with a year, one with a month, and one with a day. I'm trying to count the number of days in each year/month combination. But for simplicity's sake, the following dataset will do:

Hi folks Run; > ToothGrowth > attach(ToothGrowth) > toothgrowth=lm(len~dose) adding abline: > abline(toothgrowth) I got it done adding single abline. How to add more ablines on the same diagram?

Good morning, I have some problem adding ablines in Rstudio. The lines drew by the software doesen?t match with the added values, what can I do? pfaOK<-qcc(D[!trial], sizes=size[!trial], type="p", nsigmas=2, data.name="Polli positivi al Campylobacter") pfaOK1<-qcc(D[!trial], sizes=size[!trial], type="p", data.name="Polli positivi al Campylobacter")

Hi all, I'm relatively new to R and have a data management problem. I am importing a data matrix with some columns that have missing values. I am trying to figure out how to delete rows with NA for data FOR JUST ONE SPECIFIED column. For instance, with the example matrix: x<-matrix(nrow=5,ncol=3) x[,]<-1 x[5,1]<-NA x[3,3]<-NA how do I tell R to delete any rows with an NA value

In the example R script below, horizontal gray gridlines are drawn at y coordinates where the points are drawn with the code: panel.abline(h=y, v=xScale, col.line="gray") How do I change this so that the horizontal gray gridlines are drawn at y coordinates where the y labels are drawn? The challenge is that each panel has different y-ranges (in my real example the y-ranges and

I have been using lattice xyplot and am quite pleased, and I can use the type=c("b","g") to have it print gridlines into the page, yet if I want to have a line plot with points on it, how do I get the xYplot to print gridlines (I use Hmisc xYplot because of its bands method which allows plotting of confidence intervals). Any suggestions? I have looked at the panel functions but

Hello! I promise I looked into help files before asking. Still cannot figure it out. I think it's because I am totally confused what packages use lettice, which use trellis, etc. Sections 1 and 2 below produce the data and the data to plot. My question is about barplot in Section 3. I am trying to: 1. add only horizontal gridlines and manipulate the type and color of that line. tck = 1 is not

Hello, I have 2 variables - x and y, that belong to separate groups. I want to plot all the x and y together, but show separate abline for each group. It can be done in ggplot2, but is there a simpler way to draw ablines by group? e.g., mydata <- data.frame(x = 1:20+rnorm(20, -3, 1), y = seq(1,20,by=1), group = rep(letters[1:5],20)) plot(x,y,col=mydata$group) # need to get separate ablines

Greetings. How can I insert gridlines in the following density plot call? Must one compose a panel function?

Hi, Whats the easiest way to set a desired interval for tics on axes in R ? And will the 'grid' command put gridlines on all tics automatically ? I tend to get stuck with graphs with ranges 0-1 with only 2 tics and 2 gridlines in the 0-1 range, while I would like 10 tics (or every 0.1) tnx, Piet please reply to pvremortNOSPAM at vub.ac.be

To: silwood-r Subject: Removing lattice graph gridlines and editing label box colour Hi, Is it possible to remove the background gridlines from a lattice graph (ie graph made up of multiple individual graphs with annoying blue grid in the backgroun)?

I've used to have a script with a barplot command it in, preceded by a png: png(graph.file,height=H,width=W) barplot(t,names.arg=breaks[2:(length(t)+1)],tck=gridlines) -- worked before R 2.6.2. When I tried it in R 2.6.2, which I have for a while but didn't run with that script, it complained, the margins too large, and I've googled the messages from our list where neither

Hi, Color of my step plot is now by default. Now I'd like to change the color as the grey scale I specified. I don't know why I got three black plot. Here I attach two version of codes. The first one produces a step plot with color by default. The second one, modified from the first one, is not producing the grey scale I want. Any help would be highly appreciated.
