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

http://waterdata.usgs.gov/nwis/uv?format=rdb&period=7&site_no=021973269 I would like to be able to parse this file up: I can do this x <- read.table("http://waterdata.usgs.gov/nwis/uv?format=rdb&period=7&site_no=021973269", skip=26) but If I add another gauge to this x <-

Dear users, I have several columns of data (each column containing monthly data for a particular year from january - december) . I would wish to combine the columns to get a Single column of continuous data as shown in (b) below.

I am using R.2.4.1 on Windows XP 5.1 (SP 2). I have the following line in my R code. Analysis=anova(lm(PM ~ x)) It works the first 60 or so times it is called but then I get the following error message. Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) : 0 (non-NA) cases In order to examine the input, I preceeded the call with the following. print(PM) print(x) This gave

Hello R-helpers, I have the following code that works well, b <-list() for (i in 1:3){ a <- matrix(runif(1),3,3) b[[i]] <- a } b however, I need to do something similar with two loops and I was looking for something that would look like b <- list() for (i in 1:3){ for (j in 1:4){ a <- matrix(runif(1),3,3) b[[i,j]] <- a #but this doesn?t work } } Anyway, I wanted

Hello; I am a R newbie and would like to know correct and efficient method for doing string replacement. I have a large data set, where I want to replace character "M", "b", and "K" (currency in Million, Billion and K) to millions. That is 209.7B with (209.7 * 10e6) and 100.00K with (100.00 *1/100) and etc.. d <- c("120.0M", "11.01m",

Hi, I'm try to collect a list of methods/packages available in R for doing in-string variable/symbol substitution, e.g. someFcn("pi=${pi}"), anotherFcn("pi=@pi@") and so on becomes "pi=3.141593". I am aware of the following: ** gsubfn() in the 'gsubfn' package, e.g. > gsubfn( , , "pi = $pi, 2pi = `2*pi`") [1] "pi = 3.14159265358979,

Starting with the head of a 499 element matrix whose column names are now the labels trom a cut() operation, I needed to get to a vector of midpoints to serve as the basis for plotting a calibration curve ( exp(linear predictor) vs. : > dput(head(dimnames(mtcal)[2][[1]])) # was starting point testvec <- c("(-8.616,-3.084]", "(-3.084,-2.876]",

EPEL package but I think there's a packaging bug, thought I would ask here. Trying to build something that requires libuv-devel - it finds the .so but can't determine version. header files are in /usr/include/uv however the pkgconfig file specifies /usr/include as the include directory. The pkgconfig file also has the version so I'm not sure why the make file can't determine

Hi, I don't know what I am doing wrong to the toupper does not seem working in sub + regex. The following returns 's' not the upper class 'S' as I expect: sub("q_([a-z])[a-zA-Z]*",toupper('\\1'),"q_sviRaw") Can someone tell me where I did wrong? Thanks, Richard [[alternative HTML version deleted]]

Hello, The code below works fine up until I try to use the "IN" statement in the last line. The proper SQL format is: SELECT * FROM this_table WHERE this_column IN (1,2,3,4,5) But, I think I may be getting something like: SELECT * FROM this_table WHERE this_column IN c(1,2,3,4,5) Which makes no sense in SQL. I think it may be just a matter of string massaging, but I'm not

Hi everyone, Hi ggplot users in particular, ggplot makes it very easy to plot things given their names when you use it interactively (and therefore can provide the names of the columns). qplot(x,foo,data=A) where A has columns (x,y,foo,bar) for example but I would like to use this from inside a function to which the name of the column is given. I cannot find an elegant way to make this

Hi all, I changed the patch subject to reflect the content, becoming more general. 1) I removed the ack from Christian and Jason even far as I understand they gave it for the functionality more than for the implementation. @Jason, @Christian, please can I get back your acked-by with these changes? 2) previous patch had another name: [PATCH v3 0/1] s390: virtio: let arch choose to
