Hi David,
HELLO
WELCOME TO R
here is your code:
I'm new using R im trying to do a tukey test, but when i see the results the
p value results in NA im guessing its because i have missing values but im
not sure how to fix it
AnovaModel.2 <- aov()
If your original data.frame or your raw data have "NA's" yo
Hello,
I have little experience with r, so I wonder if someone could help me?
I need to plot a diversity measure (Fisher`s alpha) for different sites. I
calculated the values using the following commands:
Data(BCI)
alphaBCI <- fisher.alpha(BCI)
I need boxplots showing the data variation between s
Thanks to Brian's suggestion of using the logLik() function, I've dug a
little deeper. I definitely think f1 and f2 are nested models. For example,
by adding x2 to fmla1, we obtain a formula that quite clearly nests fmla1
and achieves the same log likelihood as that obtained for f2. Here is the
ext
I am just trying to split a dataframe of 750 observations of 29 variables by
"Site", which is a vector in the dataframe with five text names (ex.
PtaCaracol). I just want to generate summary statistics for my other variables
for each site individually.
I know this should be simple, and I did r
Here is an example you can use:
#Generate random normal variables to use as dummy data for Fisher's Alpha
alphaBCI<-rnorm(100)
#Assume you have 5 sites, each with 20 data points
sites<-rep(c("Site 1", "Site 2", "Site 3", "Site 4", "Site 5"), each=20)
#Making sites a factor will produce the str
Hi David
if you go

? panel.locfit
The function will do contour/wireframe like plots using par.settings
of region as well as normal 2D plots
I could not get panel.locfit to work using par.settings and created
my own panel function as panel.Locfit
at the time I did not think th
Hi David, ilai
The root cause of the problem is the passing of arguments to panel
functions to me and my colleagues.
Just going through the archives there seems to be different ways for
very similar/same outcomes and
trying to get a pattern is hard to discern.
I frequently have to use the subs

the vignette to the library(parallel) mentions snow repeatedly (esp
differences in its implementation in parallel from the original).
unfortunately, it doesn't give an example or tutorial for
multi-machine use with sockets.
could someone please point me to a simple working example, where a
