EML Analysis Tools Introduction Ecoinformatics Working Group Taiwan Forestry Research Institute (TFRI)
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 )
R-PHP – Open Source Program • http://dssm.unipa.it/R-php/
Statistical Tool • http://eml.twecoinformatics.org/modules/
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
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
Upload raw data from Local No field header Upload
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)
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
Data Check (2) Value Range Error: Select correct number type to real 1 1 Update
Data Check (3) Data Type Error: Update value ' 30.' to ' 30 ' 2 2 Update
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
