file=R/describe_nonlinear.R,line=44,col=10,[seq_linter] Use seq_along(x) instead of seq_len(length(x)).

file=R/estimate_grouplevel.R,line=87,col=121,[line_length_linter] Lines should not be more than 120 characters. This line is 128 characters.

file=R/estimate_grouplevel.R,line=99,col=28,[string_boundary_linter] Use !is.na(x) & startsWith(x, string) to detect a fixed initial substring, or, if missingness is not a concern, just startsWith(). Doing so is more readable and more efficient.

file=R/estimate_grouplevel.R,line=101,col=28,[seq_linter] Use seq_len(nrow(...)) instead of 1:nrow(...), which is likely to be wrong in the empty edge case.

file=R/estimate_grouplevel.R,line=107,col=32,[seq_linter] Use seq_len(nrow(...)) instead of 1:nrow(...), which is likely to be wrong in the empty edge case.
