  1. EML Analysis Tools Introduction Ecoinformatics Working Group Taiwan Forestry Research Institute (TFRI)

  2. EML Analysis Tools – Statistical Tool Metadata (EML) Web Base Interfaces ( Local or URL ) Raw data XSLT / DOM Database QA/QC ( MySQL ) R - PHP Output ( Web )

  3. R-PHP – Open Source Program • http://dssm.unipa.it/R-php/

  4. Statistical Tool • http://eml.twecoinformatics.org/modules/

  5. Statistical Tool – The First Module

  6. Upload EML from Local

  7. EML transforminto HTML by XSLT Metadata Display Select number type of the field Incude the field in R code ( select at least one ) ˇ Statistical Functions Raw Data Upload

  8. Number Type • Natural numbers：positive and non-zero counting numbers (i.e. non-fractions), such as 1, 2, 3 • Whole numbers：positive counting numbers and zero, such as 0, 1, 2, 3 • Integer numbers：positive and negative counting numbers and zero, such as -3, -2, -1, 0, 1, 2, 3 • Real numbers：negative and positive fractions and counting numbers and zero, such as -0.25, 3.14, 0, 1, -25

  9. Upload raw data from Local No field header Upload

  10. Data Check (1-1) • Just for numerical attribute • Data check support Scientific notation (ex. 5.0e-1) • Missing data set'NA' for R program • Data Check Functions： • Edit records with bad values • Set all the bad values to missing ( NA ) • Eliminate all the records with bad values • Ignore all the value range check problem(Just for value range error)

  11. Data Check (1-2) • Error Summary * Data type error is bold red * Value range error is bold blue • Missing Data Value If missing data value is defined by EML document,it will be converted to 'NA' type in statistical process

  12. Data Check (2) Value Range Error： Select correct number type to real 1 1 Update

  13. Data Check (3) Data Type Error： Update value ' 30.' to ' 30 ' 2 2 Update

  14. Data Check (4) Data Type Error： Value Range Error : Select 'Set all the bad values to missing ( NA )' option 3 4 5 3 • The message for Nodata error 4 5 Update

  15. Edit R Code This line can not be modified

  16. StatisticsOutput

  17. Statistical Tool – The Second Module

  18. Upload EML from URL (1)

  19. Upload EML from URL (2) Right click

  20. Upload EML from URL (3) Paste EML URL

  21. EML transforminto HTML by XSLT Metadata Display Raw Data Upload

  22. Upload rawdata from URL Data Table Right click EML Document Paste EML URL Click

  23. Data Check (1) Select 'Ignore all the value range check problem' option to update Next Page

  24. Data Check (2) Select 'Set all the bad values to missing ( NA )' option to update If no data error
