Hello, I have trouble with extracting Date string from my each row data. The date format I use is as the follows: ---------------------------------------------------------------------------- ----------- Index,Open,High,Low,Close # header 2011-11-01 9:00:00 ,248.50,248.95,248.20,248.70 ... .... ---------------------------------------------------------------------------- ----------- When I read

Hi Everybody, I am a total beginner at this so please bear with me. I downloaded by hand the file WIG20.txt (Warsaw Stock Exchange Index of 20 most important stocks). The format is this: Name,Date,Open,High,Low,Close,Volume WIG20,19940414,1000.00,1000.00,1000.00,1000.00,71600.000 WIG20,19940418,1050.50,1050.50,1050.50,1050.50,99950.000 WIG20,19940419,1124.90,1124.90,1124.90,1124.90,138059.000

Hello, I have trouble with using data.frame data. 1. I loaded data using the following: ff &lt;- read.table("E:/R/VM/matrix.txt", header=T) The data I used is attached. I want to use at least 2 conditions for selecting of data. But I failed. It works. -&gt; fff &lt;- ff[ff$HG == "GUEST",] ffff &lt;- fff[fff$WR == "READ",] But it

Hi, So far my plotting needs have been sort of ignored as I got acquainted with R this week, but now that I have the basics in place for the program I wanted to write it's time for me to start learning about how to make output that better suits my needs. I think I have two sort of charts I need to concentrate on learning how to produce: 1) Probably a trivial request - a single chart that

Hey all, Virgin post to this list - hope I've got it right ;o) I've been learning R intensively the last two weeks and gone from newbie status to *reasonably* comfortable with it. Here's an issue I just cannot solve however as it appears to be some kind of bug in R itself. But I won't claim that for sure. I have a function as follows: FindHighRow <- function(searchVector,

Hi, I was trying to make another legend for the rug plot. Sample code: library(ggplo2) ids <- paste('id_',1:3,sep='') before <- sample(9) after <- sample(1:10,9) dat <- as.matrix(cbind(before,after)) rownames(dat) <- rep(ids,3) position <- c(rep(10,3),rep(13,3),rep(19,3)) mdat <- cbind(melt(dat),position) ggplot(mdat, aes(position, value)) +

Dear all, I have a problem while working with hourly data of fx rates. I've read from a csv file, the following way: csv-file like: Date,Open,High,Low,Close,Volume 2011-08-11 03:00:00,1.41758,1.42205,1.41625,1.42174,8974 ... 2011-08-12 04:00:00,1.42175,1.42413,1.42067,1.42172,7229 ... 2011-12-30 05:00:00,1.42173,1.42341,1.42062,1.42171,6703 ... raw<-

Hello, How can I convert Close colume of the below xts time series data into a list of Close values ? I'd like to plot Close values as a list. &gt; head(zc) Close (10/15/12 09:00:00) 252.40 (10/15/12 09:01:00) 253.10 (10/15/12 09:02:00) 253.15 (10/15/12 09:03:00) 253.30 (10/15/12 09:04:00) 253.25 (10/15/12 09:05:00) 253.45 I tried the below command to plot it.

Hello, I want to add some new functionalities in the package 'quantmod '. So I download source code and am managed to build it. I found that modifying code and check if it works by repeating the following steps: 1) r CMD check quantmod 2) r CMD build quantmod 3) r CMD INSTALL quantmod_0.3-17.tar.gz 4) launch R gui 5) library('quantmod') 6) run my script Let me know if there

Hello, I'd like to convert the below time-series data with fft or wavelet related function and plot it. Could you let me know 1. How to convert xts data frame format to list format ? 2. How to plot fft or wavelet diagram ? Here is the data : &gt; class(zc) [1] "xts" "zoo" &gt; str(zc) An ‘xts’ object from (10/15/12 09:00:00) to (10/15/12 15:15:00)

Hello, I'm very interested in using financial time series data, but I'm a beginner of R programming. I'd like to fully understand internal logics on several time-series related packages such as quantmod, xts, zoo, chron, etc. So, I read some books, 'R Cookbook' and 'Art of R Programming' and another simple tutorials. But I still can't understand grammars of the

Hello, I have 1-minute time series stock data and I'd like to calculate mean of every n-th candle data of m-days. result = c(mean of 1th data, mean of 2nd data, ...) mean of 1th data = (1th data of 2012-1-1 + 1th data of 2012-1-2 + 1th data of 2012-1-3) / 3 mean of 2nd data = (2nd data of 2012-1-1 + 2nd data of 2012-1-2 + 2nd data of 2012-1-3) / 3 ... Could you let me know the fastest

Hi I have two lots of numbers which I would like to histogram using the hist() function. For comparative reasons, I want them to be on the same scale, which I can use the xlim and ylim options to achieve. However, having them on the same scale is meaningless unless they have the same "breaks". Consulting the documentation, there are 4 ways of defining the number of breaks, only one

Hello, I have questions while reviewing "chron" package(e.g.,chron.R). 1. What is the differences between 3 kinds of function definition ? 1) "name" &lt;- function(... 2) 'name' &lt;- function(... 3) name &lt;- function(... Do you know Why author used various kinds of definitions ? Is there no functional differences between them ? 2. I

Dear list: I need to reproduce a plot with three different horizontal axes. I know how to make plot with two different horizontal axes (one above, one below) using axis(): axis(1, ....) axis(3, ....) However, I don't know how to produce two axes on the same side of the plot. Any pointers or examples? -- R. Jimenez

Howdy. Been running into a bit of trouble with plotting. Seems that axes=F is not "working". Whenever I plot (either a dataframe or xts/zoo series) and I set axes=F along with xlab/ylab="" I still get the default axes printed in my chart. Consider this: #Create some sample data, both 50 units of blah series2 = c(1:50) series1 = rep(25:74) testdf1 = as.data.frame(series1)

Hello, I would like to juxtapose two lattice graphs with common X axes such that the X axes line up. I am using plot right now but the edges are not neat and it would be nice if I could just draw 1 X axis and not both of them. Here is my code: upper<-bwplot(SignalUsed~as.factor(AllNormalHitsNamesCount),data=NmlOverviewArray2, xlab="", ylab="Intensity of Individual

Hi! My question(s) in the end might be silly but I am no expert on this, so here it goes: Noy-Meir (1973), Pielou (1984) and a few others have pointed to non-centered PCA being in some cases useful. They clearly explain that "it is the case" when multi-dimensional data display distinct clusters (which have zero, or near-zero, projections in some subset of the axes) and the task is
