similar to: Iterate in a Spatial Polygon Dataframe in R?

Dear list, I have a spacialPolygonDataFrame where variables were unnecessarily imported as factors. So I am trying to unfactor variables from spatialPolygonDataFrame at data with a loop for (i in (1:length(names( spatialPolygonDataFrame)))){ command<-paste("spatialPolygonDataFrame$names(spatialPolygonDataFrame at data[",i,"])<-as.character(

Hi Ashraf, It is not obvious to me what your structures are but one problem in your function is the assignment tt1 <- SpatialLines(list(tt[[i]])). This will set tt1 to just have one item. Consider the following test.func <- function(x) { tt1 <- list() for ( i in ... ) { ... tt1[[i]] <- SpatialLines(tt[[i]]) } return(tt1) } HTH, Eric On Mon, Sep 25,

Hi Eric, Thanks for the help.But this will not solve the problem as it will generate a list and what I need is an object of class sp using SpatialLine function from sp package.So, I need to convert each matrix to coordinates and then to a line and then to a spatial line as figured in the code. My data structure is a list of 141 matrices.Each matrix represents coordinates of the river lines

Hi all,I'm trying to build a SpatialLines object from a list that contains 124 river segments. Each segment in the list contains the x,y coordinates. I'm using the following code to create the SpatialLines object, but it just retrieves one segment. Any suggestions? test.func = function(x){ ??? for (i in 1:length(x)) {??????? tt[[i]] <- x[i]; tt[[i]]? = Line(tt[[i]]); tt[[i]]? =

Hi All: I would like to generate a binomial random variable that correlates with a normal random variables with a specified correlation. Off course, the correlation coefficient would not be same at each run because of randomness. I greatly appreciate your input. Ashraf

Hi All; The following question is directed more to statisticians on the list. Suppose I have a normal random variable. Is there a transformation that I can apply so that the new variable is slightly positively skewed. I greatly appreciate your help. Ashraf

Hi there, I am getting very low throughput (around 0.29Mbps) while running netperf benchmark for guest to guest communication on a single physical host. To analyse where the time is spent in hypervisor I wanna use profiling. Please help me choosing good profiler according to my requirments. Should it be better in my case, Xentrace, gprof, xenoprof  or Oprofile. Is it possible to use some vtune
