Re: [R] save() and load()

You never created any object in R called irisdataTest. Objects in the global environment have names that are unrelated to the names of files on disk. The load function modifies an environment to create a variable named as it was named in the environment from which it was saved. Thus, you cannot

Re: [R] save() and load()

Hi, You can try this: head(irisdata) Objects loaded by load() keep their names when being saved. In your case, it is 'irisdata'. You can also use verbose = TRUE to show the names of objects loaded: load(file = "irisdataTest.RData", verbose = TRUE) Hope this helps. Regards, Shu Fai On Tue,

[R] save() and load()

Dear ALL: I am teaching statistical packages class this semester, in R programing I am trying to explain the use of save() and load() with an example using the iris data. It seems that the save() function works, BUT when I tried to load the data back to R, it seems that there is a problem(s), I

Re: [R] How to fix this problem

Using readr to read the data might let you clean it on the way in... readr::read_csv("filename.csv", col_types = list(rep(col_numeric(),6)) On Mon, 25 Sep 2023, 16:54 Ebert,Timothy Aaron, wrote: > An update please: > Collectively we have suggested removing commas from the "E..coli" column, >

Re: [R] How to fix this problem

An update please: Collectively we have suggested removing commas from the "E..coli" column, checking for different forms of "NA", and looking outside the dataset for e-trash (spaces, text, or other content). For removing commas, I would use global replace to ensure that all commas were removed

Re: [R] How to fix this problem

It looks here as though the E coli column has commas in it so will be treated as character. Michael On 25/09/2023 15:45, avi.e.gr...@gmail.com wrote: David, This may just be the same as your earlier problem. When the type of a column is guessed by looking at the early entries, any

Re: [R] How to fix this problem

David, This may just be the same as your earlier problem. When the type of a column is guessed by looking at the early entries, any non-numeric entry forces the entire column to be character. Suggestion: fix your original EXCEL FILE or edit your CSV to remove the last entries that look just

Re: [R] How to fix this problem

Dear David, simply check str(KD6). My guess (because we don't have your dataset, only a print of it) is that KD6 is not a matrix but a data.frame. The problem seems to come from the column "E..coli" which contains commas instead of periods (so text and not number). There might be other issues
