Hi all, I am trying to implement the functionality of Remember Me. The requirement is that once the user closes the browser after checking the remember me check box, it should return to the login page with username and password fields to be filled into the text boxes and the checkbox button checked, so that there is no need to fill all the fields. I am not able to fill the text boxes with user

I want to have popup menus and check boxes in my forms to let users select associated objects. In the form I''m working on, the object "belongs_to" another type of object which is selected from a popup menu. The id of the chosen object(s) for association is passed back in the parameter hash, but when rails creates a new object from this parameter hash, I get a

Hi, So I've been figuring out how to use igraph in R and like it for it's speed and simplicity. Now I have a graph built from an edgelist where vectors have a $name attribute. I have another dataframe with attributes tied to a vector ID, which is the same as the $name attribute of vectors represented in the graph. How can I iterate over the graph by V(g)$name and do

Hi Sarah, Thank you for your help. I tried using CR1<-as.matrix(CR1) but gives error Error in corrplot(CR1, method = "circle") : The matrix is not in [-1, 1]!. I am using a corrplot library. Please find the reproducible example: dput(head(CR1,10)) structure(c(26L, 46L, 39L, 38L, 47L, 59L, 56L, 61L, 43L, 60L, 78L, 63L, 2L, 58L, 8L, 1L, 1L, 9L, 11L, 2L, 1037500L, 46747L, 346300L,

Created a new data set with 3 numeric variable to find correlation CR1<- mar%>% as_data_frame%>% select(AGE, OLD_CAR_PURCHASE_YRS, Total.Spend.With.AA) had to convert it to a data frame, code: as.matrix(as.data.frame(CR1)) Now i need to run a correlation plot for these 3 variables: corrplot(CR1, method = "circle") But i am getting this error: Error in

Hi, I''m searching a metod to do a selection suck as: Select attribute1,attribute2 from table where conditions I know that the "find()" and "find_by_sql" methods takes all the attribute...But i want only attribute1 and attribute2...Can someone tell me if there''s a method that give me this opportunity? Thanks,Ivan. -- Posted via

That does clarify for me that you're missing a step: I didn't clearly follow your description at first. corrplot expects a correlation matrix, not your original data. You need to use cor() first. That's pretty clear in the documentation. See for instance the examples: data(mtcars) M <- cor(mtcars) corrplot(M) Sarah On Sat, Mar 17, 2018 at 12:00 PM Shivi Bhatia <shivipmp82 at

Dear All, Please consider the following example library(corrplot) M <- cor(mtcars) corrplot(M, method="circle", type="lower", diag=F) Suppose that I want to have the label "mpg" at the top in black and leave everything else in red. How can I achieve that? Cheers Lorenzo

Hi, I'm a newbie to R. My knowledge of statistics is mostly self-taught. My problem is how to measure the effect of users in groups. I can calculate a particular attribute for a user in a group. But my hypothesis is that the user's attribute is not independent of each other and that the user's attribute depends on the group ie that user's behaviour change based on the group. Let

I'm assuming you are using the corrplot package. If so, your data object does need to be a matrix, not a data frame. Since it's already a data frame, your line of code: as.matrix(as.data.frame(CR1)) doesn't need the as.data.frame function, but more importantly, you didn't assign the result to anything: as.matrix() does not work in place. CR1 <- as.matrix(CR1) Now try. If

Hi, I have a mysql table with fields userid,track,frequency e.g u1,1,10 u1,2,100 u1,3,110 u1,4,200 u1,5,120 u1,6,130 . u2,1,23 . . where "frequency" is the number of times a music track is played by a "userid" I need to turn my 'frequency' table into a rating table (it's for a recommender system). So, for each user, I need to categorise the frequency of tracks

Hi, I have the following data about courses (504) in a university, two attributes about the proportion of resources used (#resources_used / #resources_available), namely the average and the standard deviation. Thus I have: [1] n=504 rows [2] 1 id column and 2 attributes Here's a sample of the data: courseid,average,std 12741,1,0 17161,1,0 12514,1,0

Hi, Newbie here. I read the R for Beginners but i still don't get this. I have the following data (this is just an example) in a CSV file: courseid numstudents 101 209 141 13 246 140 263 8 321 10 361 10 364 28 365 25 366 23 367

Hello, I have an application that should be able to export a list of users as CSV. So I put Mime::Type.register "text/csv", :csv into my environment.rb, and added this code to my UserController''s index action: format.csv do require ''csv'' CSV::Writer.generate(csv_string = "", '','') do |csv| csv

Hi all, I am having 4 vectors like Data: num [1:4, 1:32] -82.8 -81.8 -75.5 -107.6 -87.6 ...  and I want to calculate the correlation between those. Is there a graphical way in R to plot the correlations or not? I would like to thank you in advance for your help Regards Alex [[alternative HTML version deleted]]

Hi all On page 39 of this paper [1] by Andrew Lo there is a very interesting correlation network diagram (sorry I dont have a more convenient link to the type of diagram I'm talking about). does anyone know of any package in R that can generate these types of diagrams?
