I have a number of strings in a vector, and want the output to be seperated by commas. > t [1] "35004" "35005" "35006" "35007" "35010" "35014" "35016" So I want want it to look like: "35004", 35005", "35006", "35007",... Can anyone help? I initially thought strsplit would be the

Dear all I am trying to make a plot in xyplot lattice by groups. I would like to show "0" in y axis but I don't want to be aligned with the x axis. I want to be a little bit above. I have tried many options but I don't get what I want. I also tried ylim=c(0, 80) but both 0 and 80 are fully aligned with the x-axis and the upper boundary of the plot, respectively: xyplot(upper.zn +

Dear Bert and all, I am really sorry. This is the full code: dat<-read.csv("example.csv")attach(dat) sdate<-as.Date(Date, format="%Y-%m-%d") #change the colour of the strip background my.settings <- canonical.theme(color=FALSE) my.settings[['strip.background']]$col <- "blue" dat_key <- list(space="right", ??????????????? lines =

1. Not reproducible since my.settings, dat_key, sdate not provided. 2. Why did you not try something like ylim = c(-5,80) ?

Not reproducible, as we have neither "example.csv" nor "Date" .

Dear all, Thank you very much for the help. ylim=c(-5, 80) worked.? Regarding the reproducible example, I used dput () and saved the file as txt. It is not the first time that I used this way and normally it works. Because when I try to attach a .csv file with the data, most of the time it doesn't go through.? I will know for the next time.? Many thanks. Regards,Maria ???? 2:11 ?.?.

My x axis is a series of daily dates (e.g., 01/01/2000, 01/02/2000, etc.) from 2000 to end of 2008. The default only gives me 4 ticks. I want more. Why doesn't this work? sdate<-as.POSIXct(strptime(date,format="%m/%d/%Y")) plot(ppt~sdate,type="l",ylim=c(0,47),col=1,lwd=1,pch=16,ylab="Salinity, psu",xlab="Year",las=1,main="Duck Key

I am a bit worried I am reinventing the wheel. Isn't there a calendar system in R? I have written a function to add months to a date and return the number of days resulting. I am newish to R so I am hoping there is a package that can do this sort of date arithmetic for me... Worik DaysInMonths <- function(s,d){ ## Days in d months from s sdate <- MSTD(s) ## Get day, month

Hi, I have a matrix with column names starting with a character in [0-9]. After some matrix operations (e.g. copy to another matrix), R seems to add a character 'X' in front of the column name. Is this a normal default behaviour of R? Why has it got this behaviour? Can it be changed? What would be the side effect? Thank you. Regards, Gilbert [[alternative HTML version deleted]]

Dear R Helpers, I am having difficulty with strptime. I wish to find the differences between two vectors of times. I have apparently no difficulty to convert the vectors to the appropriate format using strptime. But, then difftime does not calculate all the differences. Here is the code and output:- dob=strptime(as.character(datx$BDT),'%d-%b-%y'); dob$year=dob$year-100

Dear Maria The file you attached to your first e-mail did come through but I think some people on the list must have missed it.

Hello, I am having a problem using sqldf. I'm trying to choose a subset of observations from a data set based on the date and maximum value of a variable by date. Here is the code I am using: test<-sqldf("select distinct * from bextuse group by sdate having bext=max(bext)",method="raw"); The result I get back is a data frame with 0 rows and 0 columns.

Dear list, I would like to export a matrix to a TXT-File by using write.csv (not necessarily). Is there a way to add a header (with additional informations concerning the project) spanning multiple lines to this file before the actual data are listed up? Should look like this: date: filename: number of permutations: ------------ data (as a matrix) Any suggestions? Thnx in advance.

Getting the basic stuff to work is trivially simple. I can connect, and, for example, get everything in any given table. What I have yet to find is how to deal with parameterized queries or how to do a simple insert (but not of a value known at the time the script is written - I ultimately want to put my script into a scheduled task, so the analysis can be repeated on updated data either daily
