I am having a problem using boxlpot with my data. I have my data arranged in a data table, and two of my columns are "mass" and "month". I am trying to plot the mass of my study animals by...

Thank you Jim and David for your help. The 'levels' call is not a misdirection, in my actual dataset it is necessary because the flows aren't symmetrical. So while your solution is quite elegant David, it doesn't apply...

Hi All, I have a data set of daily measurements of river flow. I would like to create a "ts" object from this data. Here's a sample data set: date <- as.Date(c(1:300), format="%Y") year=as...

Hello Baptiste and others, I tried your example with my dataset, and for a few days I thought it worked for me. But I realized yesterday that the result wasn't quite what I hoped for. In my actual data...

I have a question about wireframe 3-D plots and how to apply colors. I have a large dataset of river flow (m^3/s) over time, and I have coded these flows based on their height. I would like...

Hello all, I am having a problem using augPred after I have created an nlme object. My data is 3933 rows long with no NA's, and is grouped with this function: vanfem<-groupedData(mass~age.years|name, data=av...

Hi All, I'm trying to plot data that is a time series of flows that are associated with a specific level, and I would like each level to represent a colour in a line plot. Here is some data...

Hello again, I wrote an example that better represents my data, since the coloured points are actually consecutive, but with variable lengths: date=as.Date(c(1:300)) flow=sin(2*pi/53*c(1:300)) levels=c(rep(c...

Hello All, I have a problem when I try and run an nlme model with an added correlation structure on a large dataset. This is not surprising, but I am not sure how to fix this problem. I am using...
