Hi there, I'm running R 2.0.0 on Windows 95. I'm trying to coerce a column of factors within a data frame to numeric. This is not a problem with a vector, but I can't find a way to index a column within a data frame to achieve this. All the examples from 'An introduction to R', 'S-plus 6 programmers guide', etc, use simple vectors. I'm sure I'm missing

Hello all: I have searched through the help files and I have been unsuccessful in solving this problem. I am trying to create a small wrapper function that will go around a call to a plot function and create a windows metafile in the directory and also write the name of the file to a text file. The purpose is to efficiently bring a large number of plots into powerpoint. I am using

Often it is useful to keep a "codebook" to document the contents of a dataset. (By "dataset" I mean a rectangular structure such as a dataframe.) The codebook has as many rows as the dataset has columns (variables, fields). The columns (fields) of the codebook may include: ? variable name ? type (character, factor, integer, etc) ? variable label

I've been using the following code to plot using Sweave in version 1.9.1 library(RODBC) library(lattice) channel <-odbcConnectExcel("h:/water.xls") data <- sqlQuery(channel,"select * from `Sheet1$` where Test = 'TOC' and (Valve='5010-05' or Valve='8030-V26' or Valve='1180-08' or Valve='5040-08')") odbcClose(channel) srt <-

Hi R-listers, Q1) What is the difference between the scatterplot and plot function? Q2) I am able to make a graph with the scatterplot function: scatterplot(DevelopIndex ~ Veg, + data = Turtle, + xlab = "Vegetation border (m)", + ylab = "Embryonic development index") And have been successful. But I do not know if the lines are for:

Dear R experts, I remember a similar function existed and have been mentioned in R-help before. I tried my best to search but I really can't find it out. suppose I have an data frame like this: > somedata <- data.frame(age.min = 1, age.max = 1.5, male = TRUE, l = -1.013, m=16.133, s=0.07656) In order to back up the data and I don't want to use write.table(), I would like to back

Hello All, I am trying to work on writing the following piece of (pseudo) code in an optimal fashion: ---------------------------------------------------- # Two data frames with some data a = data.frame(somedata) b = data.frame(somedata) for(i in 1:nrow(dt) { # Merge dates for a given date into a new data frame c = merge(a[a$dt==dt[i],),b[b$dt == dt[i],], by=c(some column)); }

Hi Eli, Slightly changed the example :- .section somedata .Ltmpa: .word 100 .Ltmpb: .word 60 .Ltmpc: .word 40 .Ltmpd: .word (.Ltmpa-.Ltmpb)-.Ltmpc The GNU assembler properly handles the above. $as -c x.s -o x.o $readelf -x 4 x.o Hex dump of section 'somedata': NOTE: This section has relocations against it, but these have NOT been applied to this dump. 0x00000000 64003c00

Hi all, I'm having a problem creating png images with trellis.device. I would like to create many plots with a white background using a sequence number in the file argument (i.e. "%02d"). The first plot is as expected with a white background. However, the second and all subsequent plots have a gray background. I would like all plots to have a white (or transparent)

Dear all, I am trying to use layout with xyplot and save the plot in a file. The saved file contains only the last panel (used jpg, wmf and pdf options in the savePlot function) I am not familiar with the graphic file formats and don't know if they can handle multipage output. If not do I need to loop by ndose in the following script ? Here is my script:

Hi, I have a package that contains two vignettes that both use saved objects in the examples directory of the package. With previous versions of R I could have a code chunk in the vignette like this: <<echo=false>>= load("../examples/somedata.Rdata") @ followed by a code chunk like <<eval=false>>= foo <- bar("data") @ that simulated the actual

Apologies if this is a naive beginners question. I am trying to create a dotplot with the lattice dotplot function in which my dots are colored differently depending on if positive or negative and sized by sp.nc.bdrs.data$mwZ I have tried... dotplot(sporder ~ cvarorder | direct, data=sp.nc.bdrs.data, cex=abs(sp.nc.bdrs.data$mwZ * 0.05), xlab="climate variables",

I have a linux system with Fedora Core 2 and R-2.0. I was comparing plots made with plot() and dotplot() and discovered a problem. Although the dots are positioned correctly, the numerical labels in the dotplot y axis are not correct. I put copies here: http://lark.cc.ku.edu/~pauljohn/R/plotTrouble1.jpg That is the "correct" one from plot, with the higest value on y showing at 18.

Hi, Is it possible (and how) to use a variable value to create a name of a new R variable? I want to do something like this: for (i in 1:3) { newvarialbe_#i# = somedata } where #i# is a value stored by i. In the first loop, there will be newvariable_1, in second newvariable_2 and so on. Thanks in advance, Maciek [[alternative HTML version deleted]]

For the following code below, the x-axis ticks are 1,2,3,4,5,6,7 when I was expection them to be 1,2,8,9,10,11,12. Please help me figure out where is the mistake. library(lattice) testdata <- as.data.frame(t(structure(c( 1,2005,9.24,6.18,634, 2,2005,8.65,6.05,96, 8,2004,6.81,6.51,16, 9,2004,9.0,7.29,8, 10,2004,8.84,6.18,524, 11,2004,8.54,6.35,579, 12,2004,9.97,6.3,614, 12,2005,8.75,5.84,32,

Hi I use sweave and have a problem with the following figure, but not with other figures: tt <- data.frame(c("a", "b", "c"), c(1.2, 3, 4.5)) names(tt) <- c("x1", "x2") bwplot(x2 ~x1, data = tt) ok now in sweave: \begin{figure}[H] \begin{center} <<echo=FALSE, fig=TRUE, height=5, width=10>>= lset(col.whitebg()) bwplot(x2 ~x1,

Hello, I am wondering if there is a function in R to do all possible subset selection, e.g. using AIC/BIC. It seems to me the function step can not do all possible selection. I am also want to know why the following functions give me different results. It seems I missed some points here. lm <- lm(y ~., data=somedata) AIC(lm) extractAIC(lm) Many thanks, Zheng Huang
