Using multiple dat files
"It seems therefore that there is no other way than read in individually >
100 weather tables using read.tables., right? Using file.choose() doesn't
change the work."
Yes. With that many files, file.choose() does not make sense. However, I
still do not understand what is the problem with using lapply() on the
character vector of file names with read.table() as you did in your

using [i] to plot & label all vector elements
I'm using 1.6.2 on a win 2k box. (I know I'm due for an upgrade.)
I've used brute force to label a series of vectors, and I'm wondering if
there's a better way to do this. I wanted to create a biplot of the 2nd
& 3rd PCs, and did this:
test <- edit(loadings(cv.prc.spr))
test.1 <- test[,1]
test.2 <- test[,2]
test.3 <- test[,3]

how to handle irregularly spaced data as timeseries
I have a set of modeled climate data recorded at irregular intervals.
The format of the data is such that there are monthly measurements for
the years 2000, 2020, 2050, 2080, etc. Therefore I have 12 regular
records, a skip of some number of years, then 12 more monthly records,
another skip, and so on.... I created a dataframe from .txt with the
read.table() command. For starters I need

Function that is giving me a headache- any help appreciated (automatic read )
note: whole function is below- I am sure I am doing something silly.
when I use it like USGS(input="precipitation") it is choking on the
precip.1 <- subset(DF, precipitation!="NA")
b <- ddply(precip.1$precipitation, .(precip.1$gauge_name), cumsum)
DF.precip <- precip.1
DF.precip$precipitation <- b$.data

How to replace numeric value in the column contains Text (Factor)?
The simplest would be to convert precip to character and then back to a factor if you really want it to be a factor. This will also remove the levels that no longer exist.
str(dat)
# 'data.frame': 5 obs. of 3 variables:
# $ Sites : Factor w/ 5 levels "Site1","Site2",..: 1 2 3 4 5
# $ temp : num 14 15 12 12.5 17
# $ precip: Factor w/ 5 levels

list manipulation
Hello,
I have a set of one-liners (many thanks to previous responses from this
list) that I use to look at newly imported data sets with functions like
dim(), names(), str(), etc. within lapply(). Generally, these commands
work for me but, I am apparently still missing some aspect of list
manipulation. I don't understand why I get a set of NULL list elements

Zero inflated: is there a limit to the level of inflation
Hello,
I have count data that illustrate the presence or absence of individuals in
my study population. I created a grid cell across the study area and
calcuated a count value for each individual per season per year for each
grid cell. The count value is the number of time an individual was present
in each grid cell. For illustration my data columns look something like

[RFC] Half-Precision Support in the Arm Backends
Hi Sjoerd,
For ISel, I think having a separate register class will give you less headache. I wondering if you could get away with not touching the instructions descriptions at all, instead defining external pattens for the FullFP16 case, like so:

[RFC] Half-Precision Support in the Arm Backends
I would like to revive this thread, as I am struggling a lot with the FP16
implementation in the ARM backend. My implementation in
https://reviews.llvm.org/D38315 is finished (except one case), but a more
robust alternative implementation was suggested. One can indeed argue that my
current implementation is a bit fragile, because it involves manually patching
up the isel dags for a few cases. The

combination xyplot and barchart?
Dear R community,
I am having trouble determining how to create the graph I want
utilizing my relatively limited knowledge of R. So far I have been
using the lattice library to create most of what I need.
The dataset (enviro) consists of 2 variables (Temp and Precip) for each
Day of a 2-yr period (Year). I wish to display Temp and Precip along
the y axis plotted by Day on the x axis to allow

Alignment of x-axis labels
Dear all,
I'm having trouble getting the correct spacing between x-axis labels on a barplot. This is the command I'm using to generate the plot:
temp <- barplot(precip, beside=TRUE, xaxt="n", las=1, xpd=FALSE, col="grey28", ylim=c(0, max(precip)))
Here is the structure of temp:

summing 15 minute precip data to daily
Hi all,
i'm sure there is an easy way to do this, but i'm stumped, so any help would
be appreciated.
i have a single column of data for precipitation every 15 minutes over a
year. i want to sum the precip to daily data.
so the first 96 records = the first day, the second 96 records = the second
day, and so on....
is there a way to write a for loop that would sum the data to daily, and

Spilling to register for a given register class
Ok, thanks. Except the question was meant slightly different. Less w.r.t.
organizing the register classes, and more w.r.t. implementation. I've
noticed for instance that when trying to model this straight forwardly by
writing a vreg from spills and reading this from fills (not further
elaborated here), that the spiller can't handle vreg def-use pairs: there

R combining vectors into a data frame but without a continuous common variable
Hello,
I have two different files which I'd like to combine to make one data frame
but I've no idea how to do it! The first file has two columns; one is the
date, the following is a binary code for debris flow events. Then my other
file has also two columns; the date and then precipitation data.
The thing is, is that the two date columns don't all contain the same dates.
