I recently dived into Rails and am having trouble with the link_to method. I''d like to pass some parameters to the action being called and am not sure how to do it. Essentially, I want to hyperlink a total count of bugs queried from the database to a method that will return the bug numbers when clicked on. I have a method, bug_total, that returns the total number to display in the

Hello List, Does anyone have examples of custom formatting of tables in odfweave? I know there is an example of this in the formatting.odt file that comes with the package, but running that through odfweave gives the following error: Error: chunk 13 (label=showTableStyles) Error in names(x) <- value : 'names' attribute [1] must be the same length as the vector [0] What I am really

Hi, I am trying to edit a data frame such that the string in the first line is appended onto the beginning of each element in the subsequent rows.

Hi, i'm very new to R, so sorry for what i'm sure is a very basic question. I'm producing a boxplot with the data below: df3<-data.frame( x=c(10,11,115,12,13,14,16,17,18,21,22,23,24,26,27,28,29,3,30,32,33,34,35,4,4 1,45,5,50,52,56,58,6,67,6738,68,7,8,9), fq=c(8,11,1,2,4,4,2,2,6,3,4,2,2,1,1,1,4,51,3,1,1,1,1,35,1,1,19,2,1,1,1,14,1, 1,1,10,13,5),

I am having trouble using get.bnddata() in the RArcInfo package. I installed the version 0.2 binary of the package for Windows and am using R 1.4.1 on Windows NT 4.0. I have had no problems importing and plotting arc data with get.arcdata() and plotarc(). plotpal() also works fine. I've been able to use get.arcdata(), get.labdata(), get.paldata(), get.tablenames(), get.tablefields(),

Dear R friends, I am currently working with time series data, and I have a table(as data frame) that has looks like this (TransitDate are in format = "%e-%B-%Y") : TransitDate Transits CargoTons 1985-04-01 100 2500 1985-05-01 135 4500 1985-06-01 120 1750 1985-07-01 100 3750 1985-08-01 200

I have a series of tables, one for each environment indicating a date (row) and a sample at each hour of the day (0 to 23) Test1 Table: Date,Hour1,Hour2,...Hour23 1/1/10,123,123,...,123 I would like to model this as a time series but how can I translate the table into a list such that I can get: 1/1/10 00:00, 123 1/1/10 01:00, 123 1/1/10 02:00, 123 ... 1/1/10 23:00, 123 Any suggestions on how

Hi Paul, #First I set up some sample data since I don't have a copy of your data dtOrig <- as.Date( c("1985-04-01","1985-07-01","1985-12-01","1986-04-01")) dfOrig <- data.frame( TransitDate=dtOrig, Transits=c(100,100,500,325), CargoTons=c(1000,1080,3785,4200) ) #Generate the complete set of dates as a data frame dfDates<- data.frame(

Hello, R-helpers. I have a data frame below called df. I want to add a variable c, based on the following logic: if df$a < 5 then the first two times this condition is met place a 1 in c, the next two times this condition is met place a 2 in c and when the condition is not met let c equal df$b. The result would look like, dfnew, shown below. a <- rep(c(3,5,7), 4) b <- rep(c(NA,1,2),

Dear Steve, I'll post your question also to the R-help mailing list since I think this can help to other RArcInfo users. As I mentioned in the last release of the package, I have a tutorial nearly finished. I hope to release it in the next days. > I have downloaded an .e00 file of 2000 Census Tracts for the southern US > State of Georgia, and I'm wondering which steps I need to go

Dear Eric, Hope you are doing great. I also tried the following: #First I created the complete date sequence TransitDateFrame <- data.frame(TransitDate=seq(as.Date(dataset1[1,1]), as.Date(dataset1[nrow(dataset1),1]), by = "month")) #Then I did the merging dataset1NEW <- merge(TransitDateFrame, dataset1, by="TransitDate", all.x=TRUE) Now it has, as expected the

Hi, I am a beginner in R and have only read a few chapters in the R book, I was not able to find a solution for this simple problem. I have an empty data frame: a=data.frame(name="test") which I would like to extend in a for-loop (with data extracted from a database). Ideally I would like to extend the data frame like this: a["new_1"] = 1:10 a["new_1"] = 1:12

Hi All, I have a slight issue getting R to plot a series of tables automatically. Essentially I have a series of tables that I wish to plot. They are named on_2, on_3 etc. based on the file name when they were read in. I have filelist <- list.files() to give me list of the table names. I wish to plot each table, so I was thinking along some kind of for loop as below: for (i in 1:Number_Files)

Dear all, for each A == 3 in 'df' I would like to change the variables B and K. My result should be the whole df and not the subset (A==3)... df <- data.frame(A = c(1,1,3,2,2,3,3), B = c(2,1,1,2,7,8,7), K = c("a.1", "d.2", "f.3", "a.1", "k.4", "f.9",

Hi Instead of attachments copy directly result of dput(TransitDateFrame) and dput(dataset1) to your email. Or, if your data have more than about 20 rows you could copy only part of it. dput(TransitDateFrame[,1:20]) dput(dataset1[,1:20]) Only with this approach we can evaluate your data in all aspects and provide correct answer.

Dear colleagues, I have a dataset that looks as below. I would like to make a new dataset that excludes the cases which are joint conjunctions of particular state names and years, so Connecticut and 2010, Maryland and 2010 and Vermont and 2010. I'm trying the following subset code: newdata<- subset(bpa, (!State=="Connecticut" & year<"2010")) It appears that

Hi all, I have lots of samba servers and want them to all authenticate against a single password file which will be a LDAP database.
