Re: [R] JSON to Dataframe

If those are in "ndjson" files or are indeed single records, `ndjson` functions will be a few orders of magnitude faster and will produce perfectly "flat" data frames. It's not intended to be a replacement for `jsonlite` (a.k.a. the quintessential JSON pkg for R) but it's tailor made for making

Re: [R] Merge data by coordinates

Dear Milu, If your objective is to match the places from one table to the nearest place in the second table, you can generally use knn algorithm for 1 nearest neighbourhood. But please, check what David suggests first. Best regards, Michal 2016-10-16 19:24 GMT+02:00 David Winsemius

[R] MDS, line of best fit, and id of variables

Hi, I have created a dataset that includes 28 rows (burials) and 27 columns (variables) that are coded binomially. I have gotten metaMDS to run in the pst but now can't seem to get it run at all. Error message: > mortdata.mds <- metaMDS(mortdata) Error in FUN(X[[i]], ...) : only defined on a

Re: [R] MDS, line of best fit, and id of variables

What do you get with str(mortdata)? The error message indicates that at least one of the variables is not numeric and the second suggests it is a factor. You said the values were coded binomially, but they must be numeric, e.g. 0, 1 and not "Present" "Absent" or something like that. If they are

Re: [R] MDS, line of best fit, and id of variables

You do not need to change it to numeric if it is integer. But if you want to change it, you need to follow the example I included and use sapply(). Here is my effort to replicate your error. Since I'm using random data, it fails to converge, but I do not get the error message you are getting.

Re: [R] MDS, line of best fit, and id of variables

David, I have run the str() function and all my data is int (integer). So I am trying to change it to numeric using: str(mortdata) class(mortdata) is.numeric(mortdata) mortdata.num <- as.numeric(data.frame(mortdata)) But I keep getting an error: > mortdata.num <- as.numeric(data.frame(

Re: [R] MDS, line of best fit, and id of variables

You need to spend time with an R tutorial or two. Your error is due to ignorance of basic R data structures. Bert On Oct 18, 2016 10:48 PM, "Kirsten Green" wrote: > David, > > I have run the str() function and all my data is int (integer). So I am > trying to change it to

[R] install R in relative path

Hello everyone, I am trying to figure out if I can install R in a relative path?  The reason I need to do this is to send R along to a Hadoop cluster so that I can use sparkR with the R version I shipped. The Hadoop cluster doesn't have R installed and the admin won't install it.  I tried a few
