“Error in .local(obj, …) : cannot derive coordinates from non-numeric matrix” in sampbias package in R
The error message “Error in .local(obj, …) : cannot derive coordinates from non-numeric matrix” in the sampbias package in R typically occurs when the input data contains non-numeric values or missing values.
To resolve this error, you should check the input data to make sure that it contains only numeric values and there are no missing values. You can use the is.numeric() and is.na() functions to check for non-numeric values and missing values respectively.
For example, if you have a data frame df with columns x and y, you can check if the values in these columns are numeric and there are no missing values using the following code:
# Check if values in x and y columns are numeric
if (!is.numeric(df$x) || !is.numeric(df$y)) {
stop(“Input data must contain only numeric values”)
}
# Check if there are any missing values in x and y columns
if (any(is.na(df$x)) || any(is.na(df$y))) {
stop(“Input data must not contain missing values”)
}
If the input data is not numeric or contains missing values, you can clean the data or impute the missing values before passing it to the sampbias package.
