Hello list, I posted this a few days ago on opensolaris-discuss@ list I am posting here, because there my be too much noise on other lists I have been without this zfs set for a week now. My main concern at this point,is it even possible to recover this zpool. How does the metadata work? what tool could is use to rebuild the corrupted parts or even find out what parts are corrupted. most but

Dear all: I have a shapefile in UTM coordinate system and I would like to transform it to Lat/Log coordinates (WSG84). The package PBSmapping contains function convUL to transform between the two coordinate systems when data is in the form of a data frame with attributes specifying the coordinate system. However, when shapefiles are imported using function read.shape (package maptools), a list

Hi, is there a function in R to convert data read with read.shape and which is originally in UTM coordinates into longitude / latitude coordinates? I found the convUL() function from the PBSmapping package but I have no idea how I could apply that to the read.shape object. Many thanks, Werner __________________________________________________ Do sragenden Schutz gegen Massenmails.

Hi: Is there any function in R which can convert the long/lat to UTM(Universal Transverse Mercator)? There are quite a few converters on Internet. However, the interface is designed as input->output which I can not convert lots of locations at the same time. Another question is whether there is a function in R which can tell the time zone from the location's lat/long? Thank you!

Hi, I have done the interpolation for my data and I was able to create the contours in multipanel with the help of Pascal. Now, I want to clip the contour with the shapefile. I want only the portion of contour to be displayed which falls inside the boundary of the shapefile. The data mydata.csv can be found on https://www.dropbox.com/s/khi7nv0160hi68p/mydata.csv The data for shapefile can be

Hi users, I have no clear clue about plotting spatial data. For example, I just have a table with attribute values of each grid cell, such as elevation. Then I have coordinates of the upper left corner in UTM, the number of rows and columns, and grid cell size. How to create spatial plot of elevations for the grid cells, in color ramp? Should I create a spatial grid layer with all the polygons

Dear list I'm trying to solve the following problem since 2 days with no success. Could someone help a newbie, please ? I have a dependant variable which is diameter of shell, and two factors which are level on the beach (3 levels 'B', 'E' and 'H') and a hydrodynamics indice (3 levels 1, 2 and 3) To study diameter variations according to these factors, I may use

Hi Roman, Thanks for your reply. For the spatial coordinates layer, I just have coordinates of the upper left corner, numbers of rows and columns of the spatial map, and grid cell size. How to create a spatial layer of coordinates from this data? Thanks. On Mon, Jan 15, 2018 at 3:26 PM, Roman Lu?trik <roman.lustrik at gmail.com> wrote: > You will need to coerce your data into a

You will need to coerce your data into a "spatial" kind, as implemented in `sp` or as of late, `sf` packages. You might want to give the vignettes a whirl before you proceed. Roughly, you will have to coerce the data to Spatial* (you could go for a point, raster or grid type, I think) and also specify the projection. Once you have that, plotting should be handled by packages. Here are a

>From your description, I am **guessing** that you may not want a "spatial map" (including projections) at all, but rather something like a level plot. See ?levelplot in the lattice package for details. Both I am sure ggplot2 has something similar. Apologies if I havemisunderstood your intent/specifications.

Dear R help list, ? I am working on some data from a study on the habitat use and movement patterns of fish using a marine protected area in Hawaii.? We have a number of acoustic receivers in a MPA, and any time a tagged fish passes within range it records the date and time of detection.? I am trying to make bubble plots?showing the number of detections for each fish at each receiver.? I have been

Hi useRs, I'm trying for the first time to use a sem. The model finally runs, but gives a warning saying : "In sem.default(ram = ram, S = S, N = N, param.names = pars, var.names = vars, : Could not compute QR decomposition of Hessian. Optimization probably did not converge. " I found in R-help some posts on this warning, but my attemps to modify the code didn't change

How do I create a legend with ggplot? I think should be getting the FuelTypeNum in the legend. Plot: http://r.789695.n4.nabble.com/file/n4632471/Rplot.jpeg My code is: ggplot(data=tempTable, aes(x=Bands8, y=SubPercent, fill=FuelTypeNum)) + geom_bar(position="stack", stat="identity") + scale_colour_hue('my legend', breaks = levels(tempTable$FuelTypeNum),

Dear all, I have been trying to convert coordinates from longitude/latitude to utm but I got an error. As soon as the longitude coordinate is greater than 90, I get the folloowing error message: "error in pj_transform: latitude or longitude exceeded limits" Here is what I did: SP<-SpatialPoints(cbind(126.59,-14.30),proj4string=CRS("+proj=longlat"))

Hola a todos Esta es mi primera pregunta en el grupo, y es sencilla pero me tiene atascado. Estoy tratando de cortar mi mapa de (poner limites en UTM) en un lugar definido como mi area de estudio (en este caso el sur de chile). Pero creo no estar usando bien la función CRS ponendo bien los limites requeridos. > study_area <- readRDS("CHL_adm0.rds") > study_area_UTM <-

I have a simple problem: I need to load a ERSI shapefile of US states and check whether or not a set of points are within the boundary of these states. I have the shapefile, I have the coordinates but I'm having a great deal of difficulty bringing the two together. The problem is the various GIS packages for R do not play well with each other. sp, shapefiles, maptools, etc all use different

Hi R-Users, I have plotted a region whose polygon coordinates are given in shp format ED50 UTM (zone=30) ) using "readShapePoly" in library(maptools). Now I need to plot a set of points in that region (my.dataframe, with X and Y geographic coordinates), which have been read using GPS in Longitud-Latitud form (using WGS84 system), so I first need to convert these Longitud-Latitud data

Dear List, I am trying to?plot?bathymetry contours around the Hawaiian Islands using the package rgdal and PBSmapping.?

Hi Bert, I think you are correct that I can use levelplot, but I have a question about converting data. For example, the statement: levelplot(Z~X*Y), Z is row-wise from the lower left corner to the upper right corner. My dataset just have gridded Z data as a txt file (or can be called matrix?), how to convert them to the vector in order for levelplot to use? Thanks. On Mon, Jan 15, 2018 at 6:04
