3.1 Directory with example .csv files
The example .csv file (in German format, i.e. decimals are indicated
with , and ; is used as field separator) was
exported from Umberto LCA+ (v.10.0.3.146) and attached to the R package
kwb.umberto as shown below:
temp <- system.file("extdata/umberto-lca+_v10.1.0.3.146",
package = "kwb.umberto")
dir(temp, pattern = ".csv")
#> [1] "smartech2_model-v0.1.0_input-v0.3.1.csv"3.2 Getting the data into R
Using the function kwb.umberto::import_rawdata() and
specifying the parameter csv_dir = temp)
imports the model results from one .csv file that is located in the
folder
D:/a/_temp/Library/kwb.umberto/extdata/umberto-lca+_v10.1.0.3.146.
rawdata <- kwb.umberto::import_rawdata(csv_dir = temp)

Once the data is imported into R, it can be aggregated as shown in the subsequent subchapters.
3.3.1 Grouping
data_grouped <- kwb.umberto::group_data(rawdata)
head(data_grouped)

#> # Groups: lci_method, model, process [6]
#> lci_method model process unit quantity_sum

data_pivot <- kwb.umberto::pivot_data(data_grouped)
head(data_pivot)

data_pivot_list <- kwb.umberto::create_pivot_list(data_pivot)

Finally the resulting data can be exported to an EXCEL spreatsheet.
For each lci_method available in the imported dataset a
sheet named lci_method_1 to lci_method_9 will
be created, as there are 9 distinct lci_method available
for this example data set:
- ReCiPe Midpoint (H) w/o LT - climate change w/o LT, GWP100 w/o LT ,
- ReCiPe Midpoint (H) w/o LT - freshwater ecotoxicity w/o LT, FETPinf w/o LT ,
- ReCiPe Midpoint (H) w/o LT - freshwater eutrophication w/o LT, FEP w/o LT ,
- ReCiPe Midpoint (H) w/o LT - human toxicity w/o LT, HTPinf w/o LT ,
- ReCiPe Midpoint (H) w/o LT - marine ecotoxicity w/o LT, METPinf w/o LT ,
- ReCiPe Midpoint (H) w/o LT - marine eutrophication w/o LT, MEP w/o LT ,
- ReCiPe Midpoint (H) w/o LT - terrestrial acidification w/o LT, TAP100 w/o LT ,
- cumulative energy demand - fossil, non-renewable energy resources, fossil ,
- cumulative energy demand - nuclear, non-renewable energy resources, nuclear
export_path <- file.path(temp, "results.xlsx")
print(sprintf("Exporting aggregated results to %s", export_path))
#> [1] "Exporting aggregated results to D:/a/_temp/Library/kwb.umberto/extdata/umberto-lca+_v10.1.0.3.146/results.xlsx"
write_xlsx(data_pivot_list,
path = export_path)5 Data visualisation
In addition a simple visualisation of the imported and grouped data
can be performed by calling the function
kwb.umberto::plot_results() as shown below:
rawdata <- kwb.umberto::import_rawdata(csv_dir = temp)
#> Importing csv file 'D:/a/_temp/Library/kwb.umberto/extdata/umberto-lca+_v10.1.0.3.146/smartech2_model-v0.1.0_input-v0.3.1.csv'
#> ℹ Using "','" as decimal and "'.'" as grouping mark. Use `read_delim()` for more control.

#> ── Column specification ────────────────────────────────────────────────────────
#> Delimiter: ";"

#> dbl (1): Quantity
#>

data_grouped <- kwb.umberto::group_data(rawdata)
kwb.umberto::plot_results(grouped_data = data_grouped)
