similar to: dbSendQuery with R variables

I recently started trying R and SSOAP and was able to successfully try a "hello world" service. I am now trying to get a more complicated interface to work with SSOAP and so far failed miserably at that and so need any help I can get from here. The service I am attaching is a prototype for a full service that would take information to identify a data source and a query to run and return

I doing an app to allow people to search bus time tables by bus stop and time. My models are: Providers -> Services -> Runs -> Stops <- Stations Key: "->" denotes a one to many Providers = Bus companies Services = the bus number Runs = Columns on a bus time table Stops = Cells on a bus time table, basically a time Stations = Rows on a bus time table StationA 10:00

Dear Rhelpers, Is there a faster way than below to set a vector based on values from another vector? I'd like to call a pre-existing function for this, but one which can also handle an arbitrarily large number of categories. Any ideas? Cat=c('a','a','a','b','b','b','a','a','b') # Categorical variable

Hi Rhelpers, I would like to have some help with a plot which is beyond my capabilities. This plot that I am seeking involves an overlay of two different barcharts and one xyplot. The code that I have used is the following : #save(df1,file="M:\\KBR\\df1.RData") load(file="M:\\KBR\\df1.RData") # df1$Year.ord created to obtain the right order i.e. 2015M < 2015K

Rhelpers: I'm trying to make a barchart of a 2-group dataset (barchart(x~y,data=data,groups=z,horizontal=FALSE)). My problem is that I can't, for the life of me, seem to get rid of the inter-bar space -- box.ratio set to 10000 doesn't do much. Any ideas? I'd ideally want zero space between the bars. Thanks! --j -- Jonathan A. Greenberg, PhD Assistant Project Scientist

Rhelpers: I recently installed the 64-bit version of R on my Debian system, and afterwards was asked if it was compiled using ATLAS. Is there a way to test to see if R is using ATLAS? --j

Rhelpers: Having a problem solving this. I have an xyplot call that looks like this: print(xyplot(temp_species_EAM_Pred_Pop$x+temp_species_NULL_Pred_Pop$x~temp_species_EAM_Pred_Pop$Action,main=current_species, xlab="Action",ylab="Predicted Pop", xlim=c(xmin,xmax),ylim=c(ymin,ymax),

Hello, I am having problems installing RSQLite under FC8. The error message seems to indicate Rversion.h and Rconfig.h are missing. To illustrate the problem, I have copied below the output shown when I first install R (binary distribution) and then try to install RSQLite. Because the problem does not occur when installing RSQLite with R under Windows I suspect the problem is perhaps due to my

Hello RHelpers, This may already have been answered, but despite days of scouring through the archives I haven't found it. My goal is to add multiple fitted curves to a plot. An example data set (a data frame named df in following code) is: x1 y1 factor1 4 1298.25 0.00000000 1 5 1393.25 0.00000000 1 6 1471.50

Hello RHelpers! I'm very ashamed but.... I'm creating quite a lot of plots in a big loop...each times the program ask me : > Hit <Return> to see next plot: How do I avoid that?

Rhelpers: I'm curious what the appropriate analysis to use for testing the hypothesis that two histograms are statistically different from one another? Thanks! --j

Hello Rhelpers, I am trying to represent the following data (hereafter named donnees) in a barchart with a grouping variable : site traitement date s res 1 NT 17/10/2005 normal 76.2 1 T 17/10/2005 normal 103.2 1 NT 23/11/2005 tardif 81.6 1 T 23/11/2005 tardif 98 2 NT 15/10/2005 normal 72.71 2 T 15/10/2005 normal 94.47 2 NT 15/11/2005 tardif 79.65 2 T 15/11/2005 tardif 94.7

Dear Rhelpers I have the problem with initial values, could you please tell me how to solve it?

Hello Rhelpers, I need to run the following loop over a large number of data-sets, and was wondering if it could somehow be vectorized. It's more or less a cumulative sum, but slightly more complex. Here's the code, and an example dataset (called tab in my code) follows. Thanks in advance for any suggestions! res<-0 for (i in min(tab$Date):max(tab$Date)) { if

Dear R helpers, I would like to have abline, for a lm model for example, lying within data range. Do you know how to get it? Thank in advance Nguyen D Nguyen #CODE x<- rnorm(200, 35,5) y<- rnorm(200, 0.87,0.12) plot(y~x, xlim=c(0,50), pch=17, bty="l") abline(lm(y~x)) # I would like abline is between min(x) and max(x) [[alternative HTML version deleted]]

Dear R-Users, I need a very fast and reliable database solution so I try to serialize a data.frame (to binary data) and to store this data to an SQLite database. This is what I tried to do: library(RSQLite) con <- dbDriver("SQLite") db <- dbConnect(con, "test") dbSendQuery(db, 'CREATE TABLE frames("simID" INT, "data" BLOB)') data.bin <-

R HELP, I am trying to use an R script to connect to a mysql database. I am having a problem using a variable in the where clause that contains a "space" in its value. If I include the variable inside the quotes of the query - i think it is searching for the name of the variable in the database and not the value of the variable. If I put it outside the quotes, then it complains
