difficult to answer without knowing precisely the problem. I prefer for figures used ADE4 library, which can produce more pleasing figures (but this is a personal opinion!).

a sample script:

library(vegan)

library(ade4)

nmsd

Thank you Alian, i will load those libraries and hopefully a good output will be got. Thank you too Eduard. Now can you also help will codes for building a box plot of two fish species' length and weight against time (months) at four different study sites

it is not easy to answer without knowing the shape of the data and the type of graph you want.

A site where there are example that may help:

http://zoonek2.free.fr/UNIX/48_R/all.html

or

http://www.statmethods.net/graphs/

other than the links that Alain posted, I always find the examples in the help within R a good starting point - boxplots can be made with a number of different methods, within a number of different packages, e.g. ?boxplot, ?bxp (both within the basic installation) ...

Depending on which libraries you have ever installed on your machine, the result of help.search("boxplot") varies - for me it is

ade4::sco.boxplot Representation of the link between a variable and a set of qualitative variables

fields::bplot boxplot

fields::bplot.xy Boxplots for conditional distribution

gplots::boxplot2 Produce a Boxplot Annotated with the Number of Observations

grDevices::boxplot.stats Box Plot Statistics

graphics::boxplot Box Plots

graphics::boxplot.matrix Draw a Boxplot for each Column (Row) of a Matrix

graphics::bxp Draw Box Plots from Summaries

sfsmisc::histBxp Plot a Histogram and a Boxplot

sfsmisc::p.hboxp Add a Horizontal Boxplot to the Current Plot

sfsmisc::p.res.2fact Plot Numeric (e.g. Residuals) vs 2 Factors Using Boxplots

sfsmisc::rrange Robust Range using Boxplot 'Quartiles'

sfsmisc::u.boxplot.x Utility Returning x-Coordinates of Boxplot

thank you Susanne and Alain

Hi Ssanyu,

Have you tried BiodiversityR package? You can do NMDS analysis with a graphical user interface that is easier than terminal interface. It can do also NMDS. If you check the following web site you can find the installation and manuals. You have to install Rcommander package first. It may help for your boxplots also.

Regards

thanks Sinan. i hope biodiversityR package doesnot require uninstalling the R that i getting familiar with. but i am going to check it out.

No. You don't have to uninstall R. Actually it is an R package only works with R. Good luck.
