Fitting data from a spectrophotometer.
Dear R-list,
It is not uncommon for laboratory equipment (e.g. spectrophotometers) to have a linear response in a certain interval and then go into saturation. I wonder if there is an R-function that models this; for instance by estimating the breakpoint and fitting a line below the breakpoint and a constant above.
Best regards

Converting data frame to array?
Dear List,
Please bear with a poor newbee, who might be doing everything
backwards (I was brought up in pure math).
I want to make a simple multi-linear regression on a set of
data. I did some expreiments, and if X is a 4 by 2 array and Y is a 4 by
1 array, I can do a linear regression by lm(y~x).
Now I have a tab-delimited text file with 10 rows of 300
measurements and an other file with

RCurl and kerberos
Dear list,
I would like to call a Kerberos-authenticated web-service from within R.
Curl can do it:
$ curl --negotiate -u : "http://my.web.service/"
so I would expect that RCurl also has the capability, but I have not been able to find the correct options to set.
listCurlOptions() does not return anything with negotiate, and searching the source of RCurl, the only thing I found was

1 not equal to 1, and rep command
Hi
I need to use rep() to get a vector out, but I have spotted something very
strange. See the reproducible example below.
N <- 79
seg <- 5
segN <- N / seg # = 15.8
d1 <- seg - ( segN - floor(segN) ) * seg
d1 # = 1
rep(2, d1) # = numeric(0), strange - why doesn't it print one "2"?
rep(2, 1) # 2, ok
rep(2, d1 / 1,1) # 2, this

R-help Digest, Vol 128, Issue 5
Hi Peter,
The ssconvert tool (part of gnumeric) is very good at converting spreadsheets to csv-files.
There is a wrapper in the "gnumeric" package on cran.
Cheers,
Thomas
