title: Kennedy and El-Sabaawi - Decay patterns of invasive plants and plastic trash in urban streams - R code and Data

description: Appendix Supplement A2 - R Code and Data from: Kennedy KTM & El-Sabaawi RW. 2018 Decay patterns of invasive plants and plastic trash in urban streams -Urban Ecosystems. This data was collected in urban streams in Victoria, BC, Canada and analysed using R version 3.2.5 (2016-04-14) -- "Very, Very Secure Dishes". The following details the Excel workbook contents for each tab and heading descriptions for the data in each tab. Read Me tab - the description of the data. ### Section 1: Tabs for Leaf Decay Comparisons by Stream and Type data and R code. R Code for Leaf decay k kdd tab - The R code used to compare leaf decay k and kdd by stream and by lead type, and draw plots of Leaf toughness by type and Leaf LMA by type - (copy into a new R script for use).kkcalcdd tab - the kkcalcdd dataset (save as .csv for use with R code). kkcalcddnov042015GRAPH tab - the kkcalcddnov042015GRAPH dataset (save as .csv for use with R code). kkcalcddnov042015 tab - the kkcalcddnov042015 dataset (save as .csv for use with R code). kkcalcnov52015noT0notrash tab - the kkcalcnov52015noT0notrash dataset (save as .csv for use with R code). The kkcalcdd tab, kkcalcddnov042015GRAPH tab, kkcalcddnov042015 tab, and kkcalcnov52015noT0notrash tab all have the same column headings:entry - database entry number; stream - Stream site; subsite - subsite at stream; week - week code; timeelapsed - time elapsed in days; type - litter type; pack - pack number; inmass - initial mass in grams; finmass - final mass in grams; inif - (initial mass - final mass); neglnmr - the negative ln of inif; time - time elapsed in days; dd - degree days elapsed; k - the decay rate k; kdd - the decay rate in kdd.### Section 2: Tabs for Leaf Toughness and Leaf LMA Comparisons data and R code: R Code for Leaf Toughness LMA tab - The R code used to compare leaf toughness and leaf mass per area, and draw plots of Leaf toughness by type and Leaf LMA by type - (copy into a new R script for use).
