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 part, but runs fine outside of the function: days=7 input="precip...

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 1...

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 write each value to a second object so i end up with...

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. The binary one is every day from April - October from 1900 - 2005, yet the precipitation file has dates from from say, 1911 to 2004, with some missing data on certain months and during certain years. So...

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 comparison (one year's data in each of 2 panels stacked on top of each other) between the years. Essentially what I want it to look like is an xyplot (Temp ~ Day...

label of second y-axis in xyplot (lattice)
Dear group, First I provide you with an example, I found in the newsgroup. Then I'd like to explain my problem to you by means of the output. enviro <- data.frame(Year = rep(2001:2002, each = 365), Day = rep(1:365, 2), Precip = pmax(0, rnorm(365 * 2)), Temp = 2 + 0.2 * rnorm(365 * 2)) xyplot(Precip + Temp ~ Day | Year, data=enviro, layout = c(1, 2), panel = panel.superpose.2, type = c('h', 'l')) Now my question. How can I achieve different labels for two y-...

Alignment of x-axis labels
Dear all, I'm having trouble getting the correct spacing between x-axis labels on a barplot.

variance explained by each predictor in GAM

Arranging two different types of ggplot2 plots with axes lined up
...mple way to do this? I know I could do this using facetting if they were both the same type of plot (for example, if they were both boxplots), but I haven't been able to figure it out for two different types of plots.

readMat - how to retrieve the variables

qqnorm(*, datax=TRUE, xlab,ylab) -- S+ compatibility problem
Just found because an old (written for S+) function of mine did label plots wrongly with R. Example --- inspired from example(qqnorm) --- data(precip) qqnorm(precip, ylab = "Precipitation [in/yr] ...") qqnorm(precip, ylab = "Precipitation [in/yr] ...", datax = TRUE) this is all "fine" -- `datax' is a switch that just switches the axes but keeps the meaning of "ylab labels the data axis" (i.e, when...

how to export density_function output?

Creating new data frame using loop
...ith using a "for" loop to read and separate a large dataset. The response I got worked great, but now I have another problem with using my loop. Basically I have a number of different files containing columned data. There are 132 datasets, named such that I have something in the form... precip_colxxx.txt ...where xxx is a number ranging from 1 to 132. What I want to do is read in every 13th table and extract the third column, and then place this in a new dataset. The new dataset will thus compose of 11 columns of data. I have written the following bit of script to read in every 13th tab...
