eemR 0.1.5 (unreleased)

eemR 0.1.4

  • eem_extract() is now more intuitive to use. remove argument has been replace by keep. If TRUE, the specified samples will be returned. If FALSE, they will be removed (#37).

  • eem_cut() now removes specified wavelenghts instead of keeping them.

  • eem_cut() gains an argument fill_with_na. If TRUE fluorescence at specified wavelengths will be replaced with NA instead of being removed.

  • File structure is now kept when performing inner-filter effect correction (#35).

  • Now using viridis space colors for plotting EEMs instead of color jet.

  • eem_remove_scattering() no longer tolower absorbance names and will assume that the provided absorbance spectra match exactly EEM's names.

  • Fixing a bug that prevented the interactive plot to work properly.

  • summary(x) and print(x) now return a data frame containing summarized information on EEMs contained in x. See ?summary.eemlist.

  • eem_raman_normalisation() and eem_remove_blank() will average blank EEMs if more than one are provided or found in the folder (#23).

  • eem_raman_normalisation(), eem_remove_blank() and eem_inner_filter_effect() will now verify if the correction has been already performed. If so, an unmodified EEM will be returned.

  • eem_raman_normalisation() now interpolates blank EEM to ensure that em at 350 and excitation between 371 and 428 exist (#31).

  • eem_remove_blank() and eem_raman_normalisation() will now keep blank samples when automatic correction is used. When automatic correction is used, the untransformed blank sample will be keep in the list.

  • An error will now occur if trying to perform blank correction after Raman normalization.

eemR 0.1.3

  • Interactive plot using a simple shiny app. Using plot(eems, interactive = TRUE) will lunch a shiny app that allows to interactively browse EEMs contained in eems.

  • A vignette has been added to the package whic can be viewed using vignette(topic = "introduction", package = "eemR").

  • An error will occur if one try to do raman normalization on a blank where scattering bands have been removed.

  • eem_sample_names() has been replaced by eem_names().

  • Reading Aqualog files is now ~20% faster (#26).

  • plot() gains an argument show_peaks = TRUE/FALSE which can be used to display most common fluorescence peaks used in the literature.

  • eem_remove_blank() and eem_raman_normalisation() can now try to implicitly use a blank eem from a eemlist object (#20). If blank is omitted (blank = NA), the functions will try to extract the blank from the eemlist object. This is done by looking for sample names containing one of these complete or partial strings (ignoring case): - "nano" - "miliq" - "milliq" - "mq" - "blank"

Consider the following example where there are two folders that could represent scans performed on two different days scans_day_1 and scans_day_2. In each folder there are three samples and one blank files. In that context, eem_remove_blank() will use the blank nano.csv from sample1.csv, sample2.csv and sample3.csv. The same strategy will be used for files in folder scans_day_2 but with blank named blank.csv.

    └── s1.csv

  • eem_extract() has now an argument verbose (default = FALSE) that determine if the names of removed or extracted eems should be printed on screen.

  • Implemented the generic print() method which calls summary().

  • Added tests to the packages to verify metrics.

  • Now better estimate the number of columns to read in Cary Eclipse files (#27). This also makes reading much faster.

eemR 0.1.2

  • Sample names are now exported when using the eem_export_matlab() function.

  • New function eem_bind() implemented to merge objects of class eem and eemlist.

  • Reading EEMs should be ~ 50% faster.

  • New function eem_sample_names() implemented.

    • eem_sample_names(eem) returns a vector containing the sample names of all EEMs.
    • eem_sample_names(eem) <- c(...) sets the sample names of all EEMs.

  • eem_extract() has now an argument ignore_case (#10) to specify if the regular expression search should ignore sample name case (TRUE) or not (FALSE).

  • Sample names (i.e. file names) are now verified with make.names() (#15).

  • Various improvements in documentation.

eemR 0.1.1

  • Fixing minimal R version to run the package (R >= 3.2.1)

eemR 0.1.0

  • First version of eemR
