126. On the use of R programming language in the analyses of spatial dataMilan Kobal, Andrej Ceglar, Klemen Eler, Barbara Medved Cvikl, Luka Honzak, Primož Simončič, David Hladnik, 2013, original scientific article Abstract: R is a powerful and increasingly popular programming language with strong graphical and presentation features and large expanŽdability. Although primarily intended for statistical computing, R has paved its way to the field of GIS through the development of specialized extension packages. It offers a wide range of functions at all GIS levels: data acquisition, data manipulation, graphical reŽpresentation and quantitative analysis. The paper presents R as an open source alternative to the existing commercial GIS software. It proves especially well when advanced quantitative methods on spatial data are needed (e.g. spatial modelling). We demonstrate R capabilities through spatial analysis of forest area in Snežnik (South Slovenia), where the possibilities of data import, conversion and export into various GIS formats and possibilities of geostatistics, spatial modelling and spatial visualization are demonstrated.

127. Razmerje med ksilemskim in floemskim prirastkom pri jelki (Abies alba Mill.)Luka Krže, Jožica Gričar, Katarina Čufar, 2007, original scientific article Abstract: Pri 10 zdravih jelkah (Abies alba) smo raziskali anatomsko zgradbo floemskih branik (FB) glede na njihovo širino, razmerje med številom slojev celic v FB in v ksilemskih branikah (KB) iste sezone, razlike v številu slojev celic v FBin KB po obodu posameznega drevesa ter zvezo med širino FB in KB, nastalih vistem letu, ter širino dormantne kambijeve cone (KC). Intaktne vzorce tkiv zaraziskave smo vzeli iz živih dreves v letih 2001 in 2002 ter pripravili preparate prečnih prerezov za svetlobno mikroskopijo. Ugotovili smo zvezo med širino in anatomsko zgradbo FB. Pri ožjih FB je prevladoval rani floem, pri širših pa kasni. Pri širših FB se je v kasnem floemu lahko pojavil dodatni pasaksialnega parenhima. KB so bile 2- do 21-krat širše od FB. Širina KB je poobodu posameznega drevesa bolj variirala kot širina FB. Širina dormantne KC je bila v pozitivni zvezi s širino FB in KB.
