I know @dickoa answered the question in the comments, but in order to provide at least one answer here, I wanted to go through a few simple gotchas with R on Windows. When you are using Windows, you still have to use forward slashes for paths. In R, backslashes are reserved for escaping values. So … Read more
Use the same function (cor) on a data frame, e.g.: Or, on a data frame also holding discrete variables, (also sometimes referred to as factors), try something like the following:
I have a data frame dfwith the following data: I would like to run intrinsic.pars(), so what I am doing is the following: intrinsic.pars(df$ls75cat, df$family_id_cass, df$twin_order, rscale=”ordinal”) but i get the following error: Error in eval(predvars, data, env) : numeric ‘envir’ arg not of length one What am I doing wrong?
This is because you try to access an array out of its boundary. I will show you how you can debug such errors. I set options(error=recover) I run reach_full_in <- reachability(krack_full, ‘in’) I get :reach_full_in <- reachability(krack_full, ‘in’) Error in reach_mat[i, alter] = 1 : subscript out of bounds Enter a frame number, or 0 to exit 1: … Read more
Use weighted.mean:
Then I tried: Finally, I tried: Now it shows me: Error in xy.coords(x, y, xlabel, ylabel, log) : ‘x’ and ‘y’ lengths differ It does not work, inside t, both a and b are of length 2, why it showing me x, y lengths differ?
Just in case you are not sure what @baptise means:
Let me reproduce your error in a simple way So, the next question is where are you accessing 0 index list ? (Indexing of lists starts with 1 in R ) As Molx, indicated in previous posts : “The : operator is evaluated before the subtraction – ” . This is causing 0 indexed list … Read more
e default for the parameter stringsAsFactors is now default.stringsAsFactors() which in turn yields FALSE as its default. Assuming your list of lists is called l: The above will convert all character columns to factors, to avoid this you can add a parameter to the data.frame() call:
Take a look at the write.csv or the write.table functions. You just have to supply the file name the user selects to the file parameter, and the dataframe to the x parameter:
