My objective is to look at differences in two species of fish from morphometric measurements. My morphometric measurements are head length, eye diameter, snout length, and measurements from tail to each fin. I want to use discrimanant function analyis to determine if there are differences between the two species. I am familiar with R but new to discrimannt function analysis. I want to learn

I need to make about 30 figures and I am trying to create a program in R that will make my life a lot easier. First I will tell you how my data is setup. I have 30 sites and then data for each year at the site. I have 10 years of data for each site. Below is a small chunk of my data to show the format. 2000 2001 2002 2003 2004 Site A 50 75 25 55 60 Site B 58 22 68 77 30 I am trying to

I apologize if you have already seen my question. I am new to the mailing list and I did not get any responses the first time I posted my question. However, I am not sure my post went through. Here is my situation: I have a spreadsheet with columns of fish species (text) and length (numbers). In the fish species column I have 5 different fish. I want R to calculate the mean length and

I can't figure out how to add tick marks on both my X and Y axis. For example, my X axis ranges from 0 to 1 and there are both a tick mark and a number label at the X-axis values of 0.2,0.4,0.6. and 0.8. I want to add tick marks to the figure at every 0.1 value. This will help a viewer determine the values on the x axis. I included all of my code. I apologize but it is very long. I am
