similar to: remote data access from Sweave - does not evaluate?

Dear R-users I seem to be stumped on something simple. I want to split a data frame by factor levels given in one or more columns e.g. given dat <- data.frame(x = runif(100), fac1 = rep(c("a", "b", "c", "d"), each = 25), fac2 = rep(c("A", "B"), 50)) I know I can split it by fac1, fac2 by:

I appreciate that this is OT, but I'd be grateful for pointers to examples of where Sweave has been used for web-based applications. In particular, examples of where reports/analyses are produced automatically through submission of data to a web-sever. I am mostly interested in situations where pdf reports have been produced rather than, say, a plot/table etc shown on a web page.

Dear R users, I'm a bit perplexed with the effect sort has here, as it is different on Windows vs. linux. It makes my factor levels and subsequent plots different on the two systems. Given: types <- c("PC-D-Euro-0", "PC-D-Euro-1", "PC-D-Euro-2", "PC-D-Euro-3", "PC-D-Euro-4", "PC-D-Euro-5", "PC-D-Euro-6",

Hi, I hope someone knows the answer to this or has a real good reference about it (I am using Legendre & Legendre, Numerical Ecology, 1998).... My data is a data.frame with locations as rows and vegetation assemblages / species as columns. I've done a PCA, a correspondance analysis (CA) using ca in ca package and a detrended correspondance analysis (DCA) using decorana from vegan package.

Dear R-users, I am a new user for R. I am eager to lean about it. I wanted to read and summary of the a simple data file I used the following, rel <- read.table("C:/Documents and Settings/ashta/My Documents/R_data/rel.dat", quote="",header=FALSE,sep="",col.names= c("id","orel","nrel")) summary(rel) Below is the

I'm trying to plot smooth trend using smoothTrend in OpenAir but I'm having problems. I used the following code. --------------------------------------------------------------------------------- #Set my working dir to the dir with my files setwd("c:/R") #Load the openair library library(openair) #Load the data mydata <- read.table("MCNP-pH.csv", header=TRUE,

Funciona perfecto! Gracias Carlos. Atte.

Dear colleages in R, I have earlier been working with R in Linux, where reading in a table containing Scandinavian letters ("?", "?", and "?") in the header as part of variable names has not caused any problem whatsoever. However, when trying to do the same in R running on new MacOS-X (with an Intel processor) with the same original text table does not seem to

Sri and I have been working on this over the past few months, and we've made some good progress that we'd like to share and get feedback on. Our work is based on the 'experimental-relr' prototype from Cary that is available at 'users/ccoutant/experimental-relr' branch in the binutils repository [1], and was described earlier in this thread:

Hi - I am trying to find and describe missing data in a time series. For instance, in the library openair, there is a data frame called "mydata": library(openair) head(mydata) date ws wd nox no2 o3 pm10 so2 co pm25 1 1998-01-01 00:00:00 0.60 280 285 39 1 29 4.7225 3.3725 NA 2 1998-01-01 01:00:00 2.16 230 NA NA NA 37 NA NA NA 3 1998-01-01 02:00:00

Hola Carlos, Me parece que timePlot genera los gráficos en un formato diferente. Al ejecutar grid.arrange genera el siguiente error: Error in gList(list(list(plot = list(formula = value ~ date | default, : only 'grobs' allowed in "gList" Gracias. Atte.

Greetings - I am working on some data that contain chemical names with air concentrations, and I am creating a data frame with date/time and each chemical having its own column. However, these are organic chemicals (e.g. 1-butene, 2,3,4-trimethylbenzene etc). The package I am going to be using the data with is openair, and many of the great functions require you to specify a column name which

Hii rstudio members I am learning rstudio, For my manuscript I am trying to plot CCA using species and environmental data. But I am getting error like Error in cca.default(sptrans, envtrans) : all row sums must be >0 in the community data matrix *My code is like * library(vegan) library(ggplot2) library(dplyr) rassspec<-read.csv("C:/Users/hp/Desktop/R_data/rassspec.csv",

Estoy trabajando con el paquete openair y leyendo los datos desde un CSV. Entre los campos que estoy levantando existe uno con el formato dd/mm/YYYY hh:mm por ejemplo: 19/02/2014 12:42 pm Cuando quiero consultar por fechas con las funciones del paquete openair datoscont10<-selectByDate(dato$actualizado, start="01/03/2014", end="09/09/2014") me lista el siguiente mensaje:

A simple combination of delta-encoding and run_length-encoding is one of the first schemes we experimented with (32-bit entries with 24-bit 'delta' and an 8-bit 'count'). This gave really good results, but as Sri mentions, we observed several cases where the relative relocations were not on consecutive offsets. There were common cases where the relocations applied to alternate

Eduardo, Me parece que el problema es el locale para TIME y la interpretación de %p, para no tener ese problema lo que tengo que hacer en mi caso es cambiar LC_TIME: > Sys.getlocale() [1] "LC_COLLATE=Spanish_Argentina.1252;LC_CTYPE=Spanish_Argentina.1252;LC_MONETARY=Spanish_Argentina.1252;LC_NUMERIC=C;LC_TIME=Spanish_Argentina.1252" > Sys.setlocale("LC_TIME",

I'd like to create a polar plot similar to those created by the polarFreq function in the openair package. However, this package seems to be specific to wind speed and direction, and requires a "ws" (wind speed) and a "wd" (wind direction) column. My data is unrelated to wind speed, but I'd like to be able to get a plot that does what polarFreq's plots do; I'd

In the Openair package it is possible to restore the import csv file function? it has been removed in the latest versions.
