Hello, I'm new to this list. Sorry if my question or parts of it already came up before.
For my research in geostatistics, I am working with large sets of data in R (basically large matrices containing discrete x and y coordinates and a value for a certain parameter). These sets are obtained by kriging. The operation I'd like to perform is smoothen the output data set. I want to do it by adding each data point and its 8 surrounding points and dividing this by nine (gives an average), and then replacing each element in the matrix with the result. Question 1: is there a way to address the parameter value of a single element (for example, the value for element [x=452, y=682] inside the matrix) and perform an operation on it in R? Question 2: is there a way to programm R into a loop, so that the same operation can be performed on all elements inside the matrix? Question 3: is it a problem if my data is geodata (made with the geoR library)? -- View this message in context: http://r.789695.n4.nabble.com/How-to-smoothen-a-geodata-set-in-R-tp3662902p3662902.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
