Thanks Gabor for pointing to my old version. However I got one more question
why the argument tz="" is sitting there? As you are not passing any explicit
value for that, I am assuming it is redundant. Without any tz argument, I
got following:
head(read.zoo(file="f:/dat1.txt", header=T, sep=",",
Tena koe Steven
cutData <- rbind(summary(Acut), summary(Bcut))
barplot(cutData, beside=TRUE)
should get you started. The challenge, as you identify, is to get the data
into the appropriate form and the simple approach I have used may not work for
your real data.

Do I recall correctly that there is an R package that can take an image,

thought it was an R-tool, but would appreciate any leads.
Thanks,

Michael,
Let c_1 and c_2 be vectors representing contrasts. Then c_1 and c_2
are orthogonal if and only if the inner product is 0. In your example,
you have vectors (1,0,-1) and (0,1,-1). The inner product is 1, so
they are not orthogonal. It's impossible to have more orthogonal
contrasts than you

Looking inside the code for cut, it looks like you could retrieve
the breaks as follows:
getbreaks = function(x,nbreaks){
nb = nbreaks + 1
dx = diff(rx <- range(x,na.rm=TRUE))
seq.int(rx[1] - dx/1000,rx[2] + dx/1000,length.out=nb)
}
The dx/1000 is what makes cut()'s br
Hi,
I would like to write a function that finds parameters of a log-normal
distribution with a 1-alpha CI of (x_lcl, x_ucl):
However, I don't know how to optimize for the two unknown parameters.
Here is my unsuccessful attempt to find a lognormal distribution with
a 90%CI of 1,20:

A data set I obtained has the hours running from 01 through 24
rather than the conventional 00 through 23. My favorite, strptime,
balks at hour 24.
I thought it would be easy to correct but it must be too late on
Friday for my brain and caffeine isn't helping.
TIA for a hint,
Clint

You could have posted an example of your data. You can use 'sub' to
substitute one set of characters for another in your data. There are
other ways of doing it if we had an example of your data.

Are you thinking of the digitize package?

Considering that a substantial part of analysis is related data

For this purpose, I am planning to use MySQL. Is MySQL a good way to go
