Removing missing values and a quadratic trend

This function takes an x3p object, specifically the inner polygon data frame, and performs two main operations:

1. Removes missing values.

2. Detrends the data by removing a quadratic trend.

Usage

df_rmtrend_x3p(insidepoly_df)

Arguments

insidepoly_df

A data frame representing the inner polygon. This is typically obtained from the wire::x3p_insidepoly_df function.

Value

An x3p object that contains the residuals after the removal of the quadratic trend.

Examples

x3p <- x3p_subsamples[[1]]
insidepoly_df <- x3p_insidepoly_df(x3p, mask_col = "#FF0000", concavity = 1.5, b = 1)

x3p_inner_nomiss_res <- df_rmtrend_x3p(insidepoly_df)
x3p_inner_nomiss_res
#> x3p object
#> size (width x height): 239 x 172 in pixel 
#> resolution: 6.4500e+00 x 6.4500e+00
