Error in eval(expr, envir, enclos) : object 'Rayos' not found???
Hi R-listers,
I am trying to make a trellis boxplot with the HSuccess (y-axis) in each
Rayos (beach sections) (x-axis), for each Aeventexhumed (A, B, C) - nesting
event. I am not able to do so and keep receiving:

Best method for comparing rectangles sections of beach
Hi R-listers,
I am trying to compare sections of the beach separated from the HTL to the
Veg (east to west), separated into indices (-5 to 30m), HTLIndex. Cross
parallel (north to south) are major beach sections (Rayos 1, 2, 3, 4 and
MNB). I am thinking to do an ANOVA for each independent rectangle of beach
(not exactly but will be treated as). The HTL from (0-5m) in Rayo 1 is one
rectangle of

Error in variable ' _' converted to a factor AND *tmp*
I am wondering if anyone can tell me what the error I'm receiving means
below. I thought it said that Aeventexhumed should be converted to a factor,
so I tried to do so and received the following error.
Please advise. J

Error not found - for file retrieval with head()
Hi R-listers,
I am in plyr and using the script below and when I try to pull up the .csv
file with head() it does not show up. I am not sure where I am going wrong.
I have also checked the file box for turtlehatch.csv and it still does not
show up when I head(turtlehatch.csv). Am I missing a command?

How do I compare 47 GLM models with 1 to 5 interactions and unique combinations?
Hi R-listers,
I have developed 47 GLM models with different combinations of interactions
from 1 variable to 5 variables. I have manually made each model separately
and put them into individual tables (organized by the number of variables)
showing the AIC score. I want to compare all of these models.

warning in summary(aov())
Hi R-listers,
I am receiving an error - see below. Aeventexhumed is the event in which
nesting occured, so it is defined by A, B, C. I thought as a factor was ok,
tried to change it to as.character but it still gave me the same error. Is
there something I should do about this error or just ignore it?

Interpreting script - write.csv
Hi All,
I am a beginner to R and a prof helped me with some script. I am having
trouble understanding the below line. Is it finding the file
turtlehatch.csv? I do not have my working directory set to this file. If so
I tried ("file.choose") and it did not work. R did nothing in response, no
error message with this entry and the below entry.
Can you please help me interpret? :

binomial vs quasibinomial
After looking at 48 glm binomial models I decided to try the quasibinomial
with the top model 25 (lowest AIC). To try to account for overdispersion
(residual deviance 2679.7/68 d.f.) After doing so the dispersion factor is
the same for the quasibinomial and less sectors of the beach were
significant by p-value. While the p-values in the binomial were more
significant for each section of the

aov() usage
Hi R-listers,
I am wondering if the function aov() in plyr is appropriate for two
different types of tests:
1) > summary(aov(EDI ~ VegIndex, data=data.to.analyze))
AND
2) > summary(aov(HSuccess ~ VegIndex + Aeventexhumed +
VegIndex:Aeventexhumed, data=data.to.analyze))

This is for obtaining P value and F

Q - scatterplot, plot function & trellis linear regressions???

Q1) What is the difference between the scatterplot and plot function?
Q2) I am able to make a graph with the scatterplot function:

+ ylab = "Embryonic development index")
And have been successful. But I do not know if the lines are for:

Q - scatterplots
I was able to make a scatterplot but ...
1) what does the "86" mean? The "86" shows up on the graph as well.
> scatterplot (Shells/TotalEggs ~ Sector, data = data.to.analyze)
[1] "86"
2) Also how do you change the Y axis title? I don't want it to read
Shells/TotalEggs, instead I would like it to read Average Hatching Rate (%).

lib.fixup, .GlobalEnv, and R1.5.0 (PR#1556)
Full_Name: Mark Bravington
Version: 1.5.0
OS: Windows 2000
Submission from: (NULL) (140.79.2.3)
In R1.3.1, I used the following code inside a function to set a "path" attribute
to .GlobalEnv:
env_ pos.to.env( 1)
attr( env, 'path')_ .Path # .Path is a named char vector of length 1
.Internal( lib.fixup( env, .GlobalEnv)) # adds the attribute
And this works fine. But in

search for variable in package in .GlobalEnv first
Hi
First, sorry if I get the terminology wrong, I am still quite new to the
concept of using environments and workspaces.
Say I have a statement in a package SIM like
sim <- TYPE
where the variable TYPE is initialized in the package to
e.g. "exponential" (SIM::TYPE == "exponential").
Now, I want to give the user the option of specifying the variable TYPE,
but to the

eval using a environment X but resultsin .GlobalEnv
Hello,
Suppose I have an expression, E, which accesses some variables present
in an environment V.
I do this via
eval(E,envir=V)
however all assignments end up in V. I would like the results of
assignments in E to end up in the .GlobalEnv ? Or at least the calling
environment.
Is there a quick way to this instead of iterating over all objects E
and assigning into .GlobalEnv?
Thank you
