Hi, useR- In RMySQL, how do I overwrite records? (equivalent to "replace" query). For example, suppose that dat2 is a newer data.frame than dat1. con <- dbConnect(MySQL()) res <- dbWriteTable(con, "DBname", dat1, row.names=F, append=T, replace=T) res <- dbWriteTable(con, "DBname", dat2, row.names=F, append=T, replace=T) This would not update/replace the

hi, all- i wrote a function that accept multiple arguments, but don't know how to assign names automatically. run the following code: foo <- function (...) { x = list(...) names(x) <- deparse(substitute(...)) x } a = 1; b = 2; c = 3 y <- foo( a, b, c) names(y) as you can see, only the first items are correctly named. how do i correct this problem? -- View this message in

I'm new on here, so I hope this has not been answered too many times already. I searched the knowledge base at the Wine site without finding a solution. I just switched from Mandrake to Lindows, which seems to have a capable version of Wine running. However, with two Winapps I've tried to install, the initial setup window (fullscreen, borderless, no controls) completely hides the

Hi, useRs- I have been building a set of functions over time and now my R_GlobalEnv becomes too crowded. I would like to put all my functions under the same namespace/environment. Ideally, I would like to call them using "env::func" as in C++. The following code almost do the jobs I want - except that I need to add "env$" before defining each function. I can't do

Hello, I have written a function that demonstrates the CLT by generating samples following the exponential distribution, calculating the means, plotting the histogram, and drawing the limiting normal curve as an overlay. I have the title of each histogram state the sample size and rate (1/theta) for the exponential (the output is actually 4 histograms), but I can't get the greek letter theta

Hi, useR- I am connecting to Oracle database using RODBC, but keep getting this error message: > library(RODBC) > channel <- odbcConnect(dsn="abc", uid="abc", pwd="abc", case='oracle') Warning in odbcDriverConnect(st, ...) : [RODBC] ERROR: state IM002, code 0, message [Microsoft][ODBC Driver Manager] Data source name not found and no default

Hi, I very much appreciate any help on this "fine tuning" problem in a lattice graph (I am new to LATTICE and could not find an example in the help files that worked for me. My apologies if I missed it there). I am running the following box plots to compare conditional distributions of x at different levels of y under two treatment conditions ID=1 (upper panel ) & ID=0 (lower panel

Hello all. I'm just a beginner trying to draw a boxplot and I don't know why every time I try to make it horizontal I receive the error message "parameter 'horizontal' couldn't be set in high-level plot() function". Can anybody give me an advice? Here is the code: opar <- par(ask = interactive() && (.Device == "X11" || .Device ==

Hello, I want to have the x-axis title of my plot in 2 lines, centered: experiment 1: log2(Ratio H/L) I know that in principle that works with '\n'. However, I am also using the 'substitute' command for my axis title. However, it does not make a new line. What I have so far: logbase <- 2 test <- "bait" cellline <- "cellline" plot(

Hello, In order to reduce the width of my legend in a plot I introduced line jumps in the title. Here's the problem; the legend box hasn't adapted accordingly and part of the title is printed out of the frame. See the example below: plot(1:10) legend("bottomright", bg="white", fill=c(7,8,12,13,19),

I am using R to plot baseball spray charts from play-by-play data. I have used the following command to plot the diamond: plot (0:250, -250:0, type="n", bg="white") lines(c(125,150,125,100,125),c(-210,-180,-150,-180,-210), col=c("black")) I have also plotted different hit locations using commands such as the following: points(subset(framename$hit_x,

Dear List Members, I am working on a below piece of code: Initially have created pie charts with Enlish labels to present the data for Czech Republic, now however I need to print the label with original Czech fonts. When I copy paste from Word, certain fonts get 'simplified' distorting original spelling. How can solve this problem? Is there a package I can download which will support

Hi there, I have a relatively simple question, though, I couldn't find a solution for it so far. I have a table with 1000 entries and columns containing information about different parameters for each entry. What I want to do is group all parameters from one of the columns [e.g. if all 1000 entries are grouped in 30 different categories (described as character strings) in a second column] and

The plotOHLC function in the tseries package is useful to plot timeseries of various financial assets with open/high/low/close data. I had often wondered if it could be made to run a little faster.

Hello, I have two questions: 1. How can I get black and white graphics using the pdf() device? I have tried pdf(Name.pdf, bg="white", fg"black"), but I still get full-color graphics. 2. When using lattice, how do I change the title for each panel? By default it uses the categories of the grouping factor. I would like to modify the labels in the graphic without changing

I have a question about antialiasing when R generates bitmaps. (This follows a thread on the ggplot2 mailing list.) I mostly use R on Linux, although I sometimes use it in Mac and Windows as well. On Linux, I've found that plotting shapes 15-18 via cairo results in bad-looking output. The points are not antialiased, and they are jagged and misshapen. Plots generated in Windows also aren't

Hi, I am a newbie on C++ Right now I have an array of doubles in C++. Is there a way to "export" that array into R? Of course, I can allocate the memory block first using "allocVector" and copying the array contents one by one. But, what if that array is fairly large? Copying doesn't look that efficient. I was thinking of setting the data pointer(DATAPTR) point to that

hello, useRs- i have a function that i wrote myself, for example, lag(x). however, when i load 'zoo' packages and try to lag 'zoo' object, it gave me error. (R try to pass 'zoo' object into my function.) i typed 'lag.zoo' in R, but it can't find it. how can i access 'lag.zoo' function? and in general, how can i deal with such problem as to access

Every time I recompile Asterisk (or upgrade to a new CVS-HEAD, whatever) asterisk overwrites custom files I have made. Granted, these files are named the same as the asterisk default files (vm-login.gsm, etc) because we had a person here record them to customize them a bit more for our application. Short of keeping them somewhere and copying them back every time (which isn't all that often)
