Graph question
If I have a set of data comprising a list of numbers of eggs on mosquito guts that range from 1 to 157. How can I get R to draw a barchart of the distribution of the data (i.e. x axis= number of eggs on a gut, y axis=number of mosquitoes found with that number of eggs)? Data is listed below.
Thanks,
Georgina
Number of eggs on each mosquito gut:

Can anyone advise a good transformation for this data below to produce a normalised distribution?
Many thanks,

ANOVA
I have the attached data set (csv) and I want to run an analysis of variance on the wingsize data (comparing infected vs non-infected) within and between experiments.
Can anyone help me with the command I should use?

t tests/ANOVA
I have a set of data that comprises genome numbers in single eggs from three different parasite clones - 3D7, HB3, and MIX. I can draw a boxplot of the genome numbers for each clonefed but how do I carry out a t test or ANOVA to compare if the means are signifcantly different? (Data is listed below)
Many thanks,

Two way joining vs heatmap
Hi
STATISTICA has a function called "Two-way joining" (see
http://www.statsoft.com/TEXTBOOK/stcluan.html#twotwo) and the
reference material states that this is based on the method as
published by Hartigan (found this paper:
http://www.jstor.org/pss/2284710 through wikipedia).
What is the relationship (if any) between the "heatmap" function in R
and this technique? Is there an

O(N log N) Kendall Tau
I've noticed that the implementation of Kendall's Tau in R is O(N^2).
The following reference describes how it can be done in O(N log N):

zero inflated poisson and censored-continuous models
I wonder if there is a package that will estimate a Zero Inflated Poisson
Model (ZIP), and also if there is a package that will estimate what is
called the Tobit model: that is a combination of censored and observed
values in the same sample.

Digitizing the Plot
Hi R,
Wanted to check if there are any packages available for getting the
(x,y) data points of a graph or a plot, which is in the image format.
Say, the plot could be a published report, and I want to get the points
of the curve plotted. (I am speaking something related the subject
discussed in http://www.uniphiz.com/digitizing.htm)

redirect_to("url") with post?
Is there a Rails-friendly way to redirect_to an url and post some

I''ve tried:

standard errors of fitted values are different S-plus survival pa ckage and R
Perhaps this question has been asked before: but using the function predict(
fit,type="terms",se.fit=T), where fit is a coxph object in S-plus, the
estimated standard errors are different. It may be different estimators of
the variance of the residuals? Which one is the default in R, I don't find
that too easily in the documentation. Does anybody know?
I'll be very grateful

ZFS core contributor nominations
The time has come to review the current Contributor and Core contributor
grants for ZFS. Since all of the ZFS core contributors grants are set
to expire on 02-24-2009 we need to renew the members that are still
contributing at core contributor levels. We should also add some new
members to both Contributor and Core contributor levels.

R licensing query

Problem with intermediate certificate (tls cafile)
I have several samba servers on Debian 10 all using :
samba 2:4.9.5+dfsg-5+deb10u1 amd64
I use tls cafile, tls certfile and tls keyfile with certificates from
Sectigo (https://cert-manager.com)
And when checking my connexion from the samba server, or from outside,
I've got "unable to verify the first certificate" even if tls_cafile is
provided in smb.conf.

Pseudo R squared in gls model
Dear R users,
I'm wondering if the gls function reports pseudo R. I do not see it by
summary(). If the package does not report, can I calculate it in this way?
Adjusted pseudo R squared = 1 - [(Loglik(beta) - k ) / Loglik(null)] where
k is the number of IVs.
Thanks!

Fibonacci
Hi!
I am trying to work out the code to get a Fibonacci sequence, using the
while() loop and only one variable. And I can't figure it out.
Fibonacci<-c(1,1)
while (max(Fibonacci)<500){
Fibonacci<-c(Fibonacci, (max(Fibonacci) + ?(Fibanacci)))
}
How can I tell R to take the value one before the max value? (Without
defining another variable)
(Probably super easy... I am a

[LLVMdev] parallel loop metadata question
I propose that we change the first paragraph of http://llvm.org/docs/LangRef.html#llvm-mem-parallel-loop-access-metadata:
---
For a loop to be parallel, in addition to using the llvm.loop metadata to mark the loop latch branch instruction, also all of the memory accessing instructions in the loop body need to be marked with the llvm.mem.parallel_loop_access metadata. If there is at least one

Will do. I will write something up.
Hal, your concern below isn't so much with the proposed semantics but rather with the use - that optimizations must respect the loop for which the metadata applies, correct?
Thanks

[LLVMdev] Proposal for ""llvm.mem.vectorize.safelen"
Yes, I think the 2 outcomes are:
- the current spec is unclear and will be clarified
- in order to support safelen() and even the simd construct itself, LLVM will require infrastructure work to know when a lexically backwards dependence may have been introduced.
