Hello, I want to reduce the distance between my ticks and their labels. I managed to do it for the x-axis, but the y-axis puzzles me. Here's an example where there is no space between the x-asix ticks and labels. par(las=1) plot(runif(50), type="l",xaxt="n",yaxt="n",ylab="", bty="l") axis(2) axis(1,padj=-1.5) #However, axis(2,padj=-1.5)

Hello, I have an excel file that I load through RODBC. Some of my columns are blank. They are equity time series and the stocks did not exist at the earlier dates. My problem is that the whole column becomes <NA> even though there are numbers at later dates.

Hello, Let's say I have 50 R scripts to run. What would be the most efficient way to run them? I thought I could do multiple Rterms in a DOS batch file: Ex: Rterm <1.R> 1.txt Rterm <2.R> 2.txt ... Rterm <50.R> 50.txt However, I'm afraid they will all open at the same time. I know I could pause the batch file with something like: PING 1.1.1.1 -n 1 -w 60000

Hello, How do you change the language of the labels in a graph. In this example, I want to get French labels by changing Sys.putenv. I should get "Mai" instead of "May". Sys.putenv(LANGUAGE="fr") x <- as.Date(c("1jan1960", "2jan1960", "31mar1960", "30jul1960"), "%d%b%Y") y <-1:4 plot(x,y) Regards, Pierre

Hello, I need to identify all elements which have a sequence of 3 consecutive upper case letters, anywhere in the string. I tested my grep expression on this site: http://regexlib.com/RETester.aspx But when I try it in R, it does not filter anything. str <-c("AGH", "this WOUld be good", "Not Good at All") str[grep('[A-Z]{3}',str)] #looking for a

Hello, How would you export a 3-dimensional array to an SQL database? a<-array(1:24, 2:4) Is there an open source DB that would be more adequate for this type of operation? Is there a way to reshape/flatten a 3-dimensional array?

Hello, This is not a problem with R, the calculated results are mathematically correct. This a matrix stability problem. Because of measuring errors, my matrix solution is a bit off. Here is what my equations look like: A11 x11+A12 x12 +A13 x13 = b1 A21 x21+A22 x21 +A23 x23 = b2 A31 x31+A32 x31 +A33 x33 = b3 A is a reading, X is a measured weight, and b is total. The 3 experiments give

Gregexpr - extract results with lapply Hello, I need to extract sequences of three upper case letters in a string. In other words, in this string: str <-c("ABC", "this WOUld be gOOD") The result I'm looking for is ABC WOU OOD. With gregexpr, I can get the position and length of the sequences gregexpr('[A-Z]{3}',str,perl=TRUE) [[1]] [1] 1

Here's my contribution to R. When R interacts with external programs (MySQL, cURL, etc.), it often requires a pasted string that is sent to these programs. For readability reasons, it is often preferable to have complex commands (SQL for example) spread on several lines. However, the normal paste function requires to add additional ' ", ' at the end of each line and another '

First of all, I apologize for the triple post, but I did not see that the word wrap on the r-help list site would render my code unusable. So here it is again. Hoping that this time it will work if you cut and paste it in your Rgui. I have a program that works well in Rgui but that does not work in a batch file (Execution halted). Here's the code (it will work on your R, but you need

Hello, I'm dealing with financial time series. I'm trying to find out X in this sentence: The most recent close is the lowest level since X(date).

Hello, I'm trying to get a few turnpoints for a financial time series. There is a function in pastecs that does that. However, I get a large number of turnpoints: library(pastecs) data(EuStockMarkets) dax <-EuStockMarkets[,1] plot(dax) turnp <-turnpoints(dax) summary(turnp) #gives 925 peaks/pits!!! How can specify to get only 30 turnpoints? Second question: the extract function

Hello R-helpers, What I have: I am working with vectors not matrice: #Basic equations A <-c(-20,-9,-2) x <-c(0.17,0.22,0.61) B <- crossprod(A,x) # R matrix multiplication works with vectors A%*%x==B # Is true...
