having issue with coordinates function

[fary]

hello everybody
I am new to r and trying to clean geocode data which is storede in two columns, Longitude and Latitude.
the data are entered in different shapes:
"547140"
"35.6997"
"251825.7959"
"251470.43"
"54/4077070001"
"54/305495"
I don't know how to clean this variable with this great difference.
when I want to use the coordinates function I get this error.

coordinates(dt) <- ~GPRSLongitude+GPRSLatitude

Error in coordinates(dt) <- ~GPRSLongitude + GPRSLatitude :
could not find function "coordinates<-"

What packages are you using? Is this in a data frame? You have a mix of formats there, do you know what CRS they are in meant to be in (the first four anyway).

You've had three topics with pretty much the same question. Why didn't you just edit the first one?

A reproducible example would be useful:

FAQ: What's a reproducible example (`reprex`) and how do I create one?

Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it and feel your pain. Then, hopefully, folks can more easily provide a solution. What's in a Reproducible Example? Parts of a reproducible example: background information - Describe what you are trying to do. What have you already done? complete set up - include any library() calls and data to reproduce your issue. data for a reprex: Here's a discussion on setting up data for a reprex make it run - include the minimal code required to reproduce your error on the data…

could not find function "coordinates<-"

We can solve this at least, because it comes by not having any function called coordinates loaded. i.e. there has been no library(somelibrary) or require(somelibrary) which would be needed to load whatever library contains the coordinates function we require to use.

i installed these packages
library(sf)
library(geoR)
library(sp)
library(gstat)

right so if its sp this should work, and coordinates would be found.

library(sp)

data(meuse.grid)
coordinates(meuse.grid) <- ~x+y
