debug_ascii: Debug errors when converting ASCII files with the readroper package

Description

A common issue when converting ASCII files is getting the column positions, variable widths, and new variable names to align. A simple way to debug errors is to compare the lengths of each which must be equivalent to convert ASCII files with the readroper package. debug_ascii calculates the lengths of each of these inputs so you can quickly diagnose errors. Each argument can be copied directly from the 'read_rpr' function within the readroper package.

Usage

debug_ascii(col_positions_input, widths_input, col_names_input)

Arguments

col_positions_input

The col_positions argument in the read_rpr function

widths_input

The widths argument in the read_rpr function

col_names_input

The col_names argument in the read_rpr function

Value

A dataframe containing the lengths of the col_positions, widths, and col_names arguments

Examples

# NOT RUN {
For ease of replicability, the examples here
come from generated data rather than data from
an ASCII file.
# }
# NOT RUN {
col_positions <- c(1, 2, 3, 5, 8)
widths <- c(1, 1, 2, 3, 1)
col_names <- c("Q1", "Q2", "Q3", "Q4", "Q5")

debug_ascii(col_positions, widths, col_names)

# }
# NOT RUN {
Now, if the lengths differ from an error
(see the missing "Q4" variable), the function
will throw a warning.
# }
# NOT RUN {
col_positions <- c(1, 2, 3, 5, 8)
widths <- c(1, 1, 2, 3, 1)
col_names <- c("Q1", "Q2", "Q3", "Q5")

debug_ascii(col_positions, widths, col_names)
# }
