...and coding Ruby in Rails, however it''s my 3rd day with this beast :) so I''m asking : When I added protected methods to the model before it was like: protected method.................... end Would this be a valid way to write a protected method as well ?: attr_protected :column1, :column2 Perhaps this particular call is already protected inherent to the call, yet do I need to surround it with "protected" and "end" ?

Hello, Is it possible to scroll a canvas that has a column of listboxes in it? Does scrolling only work with listboxes and text widgets? The following code displays the scrollbar, but - it has no thumb - does not respond to mouse clicks. - the vertical height of the tkcanvas (i.e. column1) is unconstrained. It's lower edge is out of view, and the lower button on the scrollbar is out of view. I expected the scrollbar and canvas to have a height of 200 pixels and to be able to use the scrollbar to bring different listboxes into view. I created this from examples on the forum, but...

is there a smart way of determining the number of pairwise present data in a data matrix with missings (maybe as a by-product of some statistical function?) so far, i used several loops like: for (column1 in 1:99) { for (column2 in 2:100) { for (row in 1:500) { if (!is.na(matrix[row,column1]) & !is.na(matrix[row,column2])) { pairs[col1,col2] <- pairs[col1,col2]+1 } } } } but this seems neither the most elegant nor an utterly fast solution. thanks for suggesti...

Hello to all is there a function wich splits a data.frame (column1,column2,column3,....) into data1 <-(column1,column3....) #column2 = 1 data2 <-(column1,column3....) #column2 = 2 data3 <-(column1,column3....) #column2 = 3 ... Regards Knut

I am writing a custom function that uses an R-function from the reshape package: cast. However, my question could be applicable to any R function. Normally one writes the arguments directly into a function, e.g.: result=cast(table1, column1 + column2 + column3 ~ column4, mean) (1) I need to be able to write this statement as follows: result=cast(table1, string_with_columns ~ column4, mean) (2) string_with_columns = group of functions that ultimately outputs: "column1 + column2 + column3" Statement 1...

Hi all. I am wrting a small content management tool for my company and was trying to display some images from our file store shown below. <td> <img src="\\xx.xx.xxx.xx\xx\xx\xxx\abc.gif"/> The app was displaying the image when it is under the \public\images directory. Is there anything special we need to do to get a file from outside the root of the application? Any help

...be "Yes", however if any one of the three existing variables is a "No", then then new variable should be a "No". I would then use that new variable as an exclusion for data in a new or existing dataset (i.e., if NewVariable = "No" then delete): Take this: Column1, Column2, Column3 Yes, Yes, Yes Yes, No, Yes No, No, No No, Yes, No Yes, Yes, No Generate this: Column1, Column2, Column3, NewVariable1 Yes, Yes, Yes, Yes Yes, No, Yes, No No, No, No, No No, Yes, No, No Yes, Yes, No, No And end up with this: Column1, Column2, Column3, NewVariable1 Yes, Yes, Yes,...

Hi, I have written boxplot commands of this form before, but I don''t quite understand why the function call is reporting a syntax error in this instance. All parameters passed to the function are strings. Thanks in advance.

I have a dataset called "raw-data" . I am trying to use the following code - col_name<-names(raw_data) for (i in 1:(length(names(raw_data))-2)) { tbl=table(raw_data$Pay.Late.Dummy, raw_data$col_name[i]) chisqtest<-chisq.test(tbl) } Say the 1st column of my raw_data is Column1. The idea is when i=1 then raw_data$col_name[i] will automatically become raw_data$Column1 , which is not happening.

Hi all, Ive got a database with 10 columns (different variables) for 100 subjects, each column with different # of NA's. I'd like to know if it is possible to use a function to exclude the NA's using only a specific column, lets say: Data2 <- omit.exclude(Data1$column1) ??, then Data3 <- omit.exclude(Data1$column2) and so on I tried the code above but with no results Thanks for any help CM __________________________________ Yahoo!

...several times and like the results it gives me. I am now trying something with it that I have not been able to get to work. For any n column matrix I would like to run this function on those n columns and store the results. For example, if my matrix has 1 column then this is just expand.grid(x = column1). If my matrix has two columns, then I want expand.grid(x = column1, y = column2), and so on for any number of columns... In a program I am writing, the user can specify any matrix. Does anyone know of a way for R to calculate this based on what the input matrix is? e.g. if this user gives a 3...

Hello, Can someone kindly tell what the heck creating a relationship does in active record? I understand the idea of joining the tables and such. But how do I use it? Is it available in a scaffold? How about when I want to view a record and want to see all the joined data from the other table? Do I have to manually code the data I want from the other table? Does this automatically make the
