Hello,
I'm trying to make a non-linear regression using the attached data and
this model. When I run it I get the following message:
Error in nls(y ~ 1/(a + w * x), data = df, start = list(a = 1, w = 1), :
singular gradient
mod - nls(y~1/(a+w*x),data=df,start=list(a=1,w=1),trace = TRUE)
Hi there,
This seems like it should be simple. I have a data frame of climate data
sampled every 10 min. I want to average the entire data frame into 30
min values (i.e., one value for each half hour). Functions like
running.mean give me a moving average but I want to reduce the size of

Hi there,
I'm running R on windows 7 with Rstudio. Everyday I receive a zip file
where a bunch of half-hourly files are zipped together.
I then use
xx=unzip(ind)
to get xx, which consists of :
[1] ./2011/A20112961503.flx ./2011/A20112961503.log
./2011/A20113211730.slt ./2011/A20113211800.slt
Great, many thanks.

Yes.
Now, it you would follow the posting guide and give the 'at a minimum'
information you were
into making this possible in R).

Good point.
Here is the code
plot(dat$timestamp,dat$delta_18_16, ylab=, xlab=(min), tck=0.05,
col=blue)
mtext(side=2, line=1.5, expression(*delta*^18*O [\u0089]), cex=1,

Hello,
I'm trying to load a weeks worth of files that are each named by the
date they were creaded (e.g., 20110601.RData), starting with the day
before today so if today is June 1, I would like to load 20110525-
20110531. The script was working until today, and x= 20110593 20110594
20110595

Hello,
I would like to split the attached data frame based on the DATE
variable. I'm having a real problem doing this. I am able to split
iso-read.table(datuh.dat, header=TRUE, sep=, dec=.) #load
mylist=split(iso,iso$DATE) #split
str(mylist) #result seems a bit odd
However, after splitting
Hi John,
First off, thanks again for your help with this. Much appreciated.
I've attached a file of the original data (yes, as you can see there are
header names). These hour long files are zipped together on a computer
(which is actually an analyzer) and sent each morning to a server. I

I have files (see attached) which are created daily. I want to load
