LaF version 0.8 =============================================================================== * Detects and ignores byte-order-mark * Added option to ignore (set NA) fields that could not be converted; previously this generated an error. LaF version 0.7 =============================================================================== * Fixed memory leak * Added option to show progress bar in process_blocks LaF version 0.6.3 =============================================================================== * Minor update. Fixes error in detect_dm_csv with sample = TRUE. As reported by spinwards. LaF version 0.6.2 =============================================================================== * Minor update. Fixes error with '~' in the path name. LaF version 0.6.1 =============================================================================== * Minor update. Fixes bug in the C++ code. This bug only affected colfreq and colnmissing one some platforms when there are missing values in the numeric columns. LaF version 0.6 =============================================================================== * Internal changes: switched documentation to roxygen; changes to namespace and description files to pass tests. LaF version 0.5 =============================================================================== * Added ability to use data models for opening files. These contain a description of the column names and column types etc. The data models can be saved to and read from YAML-files. For CSV files the data models can also be automatically detected. Blaise data models are also supported. (see laf_open, write_dm, read_dm, read_dm_blaise, detect_dm_csv) * The ability to set the levels of columns. When reading these columns are automatically converted to factors. * Some routines were added to read specific or random lines from a text file (see get_lines, sample_lines) and to determine the number of lines in a text file (see determine_nlines). * Fixed bug with nrows, which could return the wrong number of lines when the size of the file exceeded 2 Gb. LaF version 0.4 =============================================================================== * Added methods for the calculation of simple column statistics such as mean, sum, number of missings, frequency table, min, max. * Fixed bug in skip option in laf_open_csv on windows machines with files with DOS-line breaks * laf_open_csv and laf_open_fwf now also accept r'isch column types: numeric, and factor instead of double and categorical. * Fixed bug with checking if file can be opened on some windows network shares LaF version 0.3 =============================================================================== * Fixed bug with categorical columns. The levels of the categorical columns not always match those in the file. * Added option to laf_open_fwf and laf_open_csv to trim white space from string and categorical columns. * Added option to laf_open_csv to skip the first lines in the file. * Added ability to read floating point numbers in scientific format. * Added tests.
