Hello, I would like to ask if anyone could help me. I want to save images I create (e.g. histograms, boxplots, plots, etc.) to a file or files. Does anyone know how to do this? Thank you. Aiste [[alternative HTML version deleted]]

Hello, I have a problem with using read.csv(). I want to read a table from the ONS neighborhood statistics website which has an address:

Greetings! I''m trying to update a set of records from the same model on one form. The AWD book gives an example on p.356 but I guess I''m not understanding it. I can see from the error message I''m getting that the controller is receiving a hash of hashes back from the view, and that it''s got the stuff I expected (two values per record that was sent to the

hi, i have 2 tables (counties and towns). counties has_many towns and towns belong_to counties. now my question: i thought i would need to do is say @counties = Counties.find(:all). should that not return to me all counties in the counties table WITH all towns associated with each county? in my view i was getting error when doing this if(counties.has_towns?) saying undefined has_towns

I''m trying to update records in a table based on data I get back from a form. In the simplest case, the params structure returned from the form is: {"illness"=>{"1"=>{"illness_date"=>"", "qualifier"=>""}}} The controller code works (i.e., updates the first record) when I do the following: params[:illness].each do

I am working on a simple pilot project comparing the capability of SQL, SAS and R to perform a rolling mean per the following instructions. I have completed the SQL and SAS analysis, so now it's R's turn. Calculate mean values of x (x=count) for each date in the dataset where mean = the average count of days [t-9] through day [t-3] for each date/illness combination. Dataset aggpilot

Please let me know if this is or is not the right place to ask these types of questions. Warning: I am new to R by two days. I have a simple dataset. I have loaded the dataset successfully using the following code: Filepath=(C:\temp\\pilot\dataset1.txt") Pilot=read.table(filepath, header=TRUE) Dataset1.txt is delimited and looks like this: Date illness count 2006/01/01 derm 17 2006/01/01

An organization has asked me to comment on the validity of their recent all-employee survey. Survey responses, by geographic region, compared with the total number of employees in each region, were as follows: > ByRegion All.Employees Survey.Respondents Region_1 735 142 Region_2 500 83 Region_3 897 78

hello, i am having trouble on how to implement this. i have a table of doctor information where each doctor has a town and county field. i would like to create a view that shows the amount of doctor_types in each town. For example if the user selects the ''General Doctors'' search button, a view like this will show up. The next step would be for the user to select which

After installation of R into VineLinux2.1.5, I started to enjoy statistics following some instruction, and found it very useful. One of my main purpose to use R is to try spatial statistics. Since library named "spatial" has already installed, I just tried ... > library(spatial) > towns <- ppinit(test.dat) ------- test.dat ------- x,y 4,7 5,7 5,8 5,9 6,7 6,8 6,9 7,8

Hallo to everybody, I would like to perform an analysis but I don't know how to proceed and whether R packages are available for my purpose or not. Therefore I'm here to request your support. *The idea is the following:* I noticed that the names of the towns and villages in northern Italy most of the time sound differently from names of cities based on southern Italy. Just to give you an

Good day all I have figured out most/basics of asterisk.I went with sip and made my own sip.conf and extensions.conf No I have 2 servers running sip in different towns.Both is connected with static ip so thats fine,but now. Lets say someone want to call someone else in the other town.How do I get asterisk to know,for instance sip extension 101 is on another sip server on a different ip. And I

I just discovered the great piece of software that is available with the survey package. Many thanks and 'Hats off' to Thomas Lumley. While package survey covers analysis of features of objects sampled (in clusters, strata) I could not find analysis of features of repeated relationsships between sampled objects (in clusters, strata). My understanding is that it is not adequate to treat

Dear list, I have a long list of towns in Africa and would need to get their geographical coordinates. The Google query [/TownName Country coordinates/] works for most of the TownNames I have and give a nicely formatted Google output (try Ingall Niger coordinates for an example). I would like to launch a loop on the list of names I have and automatically extract the coordinates given by Google.

Hello, I would like to know if (as the usa map with Splus), it is possible with R to plot the french map and to add points (representing towns for instance) on the figure in the appropriate (x,y) system. Thank you. Nathalie Peyrard

What kind of special magic does glm have? I'm working on a logistic regression solver (L-BFGS) in c and I've been using glm to check my results. I came across a data set that has a very high condition number (the data matrix transpose the data matrix) that when running my solver does not converge, but the same data set with glm was converging ( I love R :) ). I noticed that glm using

I'm fitting some small data sets using a binomial glm with complementary log-log link. In some ill-conditioned cases I am getting convergence failures. I know how to adjust maxit and epsilon, but that doesn't seem to help. In fact I know some very good starting values for my fits, but I can't see how to get them in to glm(). How may I do this? -- Dr Murray Jorgensen

Hello. I must fit a logistic regression to data in the form of proportions, but in which some of the proportions are zero. I therefore cannot use the glm function with a binomial link since the link function is not defined for p=0 or 1. What other solutions are available? Any references to this specific problem (i.e. regression using proportions, of which some are zero) would be welcome.

I am hoping for some assistance with formatting a large text file which consists of a series of individual records. Each record includes specific labels/field names (a sample of 1 record (one of the longest ones) is below - at end of post. What I want to do is reformat the data, so that each individual record becomes a row (some cells will have a lot of text). For example, the column
