Hello all   I have a geology map that has three level, bellow   <-geology lithology    landscape   landform     landform level is used as covariate (with codes=1,2,3,4,5) for training of neural network, but this level has missing data as NA. I want to replace the missing data of landform level with 0 (zero). Finally, landf...

Hi, I have a 3-d geology problem. I have an xyz fault data set. I am able to view the data set in R using plot3-d but cannot create a raster from it. I need to create a raster and export so that it can be read in arcscene. Can anybody help? Thanks -- Shane [[alternative HTML version deleted]]

Hi, I am interested in ggplot2 and I found this lattice code very interesting (http://addictedtor.free.fr/graphiques/graphcode.php?graph=48). Code: library(lattice) lattice.options(default.theme = canonical.theme(color = FALSE)) tmp <- expand.grid(geology = c("Sand","Clay","Silt","Rock"), species = c("ArisDiff", "BracSera", "CynDact", "ElioMuti", "EragCurS", "EragPseu"), dist = seq(1,9,1) )...

Can someone point me to an implementation of the "runs up and runs down" test, or does such beast exist in R? From web searches the "runs up and runs down" test is commonly used for testing pseudo-random number generators and in simulations. John C. Davis describes its use in geology in his book on geological statistics (2002). Having searched the full site, I can locate only the "runs.test()" in the tseries package. JWDougherty

Dear R users, If I manage to sort out this graph, it is certainly a candidate for the new R graph gallery (http://addictedtor.free.fr/graphiques/displayGallery.php)! I created the following lattice graph: library(lattice) tmp <- expand.grid(geology = c("Sand","Clay","Silt","Rock"), species = c("ArisDiff","BracSera","CynDact","ElioMuti","EragCurS","EragPseu"), dist = seq(1,9,1) ) tmp$height <- rnorm(216) sps <- trellis.par.get(&quot...

I am trying to plot a non-linear trend line along with my data. I am sure the solution is simple; any help greatly appreciated. Recent and historic attempts: fit = nls((sd~a+b*exp(-c/time)+d*geology), start=list(a=1, b=1, c=10, d=-1), model=TRUE) plot(time, sd, col=3, main = "Regression", sub=formula(fit)) lines(time, fitted.values(fit), lwd=2) #tt = seq(from=0, to=200, by=10) #lines(time, predict(fit, time=tt)) #lines(time, predict(fit))

Hi I am using the quantreg package for median regression for a large series of subsets of data. It works fabulously for all but one subset. When it reaches this subset, R takes the command and never responds. I end up having to kill R and restart it. It appears to be something with the particular data subset, but I can't pinpoint the problem. Here are some details Operating system:

Dear All   I want to import the vector file (   .shp) to R. I could import the file by rgdal package before, by following:   geology<-readOGR('C:/geology//saga/geo.geom','finalgeology')   but now there is an error:   Error in ogrInfo(dsn = dsn, layer = layer, input_field_name_encoding = input_field_name_encoding) :           GDAL Error 4: .shx file is unreadable, or corrupt.   Can you tell me where is the p...

...r (ie.e closer that 50 meters) to see if they are similiar lithologicaly. I thought maybe this can be done with some kind of multiple regression analysis where one would test if layers (ie. Clayey layer in Bhole 1 in depth 5m and in Bhole2 this layer is in depth 7 meters) are in same depth and if geology on that depth is the same in Bhole1 as in Bhole 2. For example if boreholes would have similiar lithology on similar depth that the regresion R^2 would be 1 and if not that it would be less than 1. This is of course my idealized way of approaching the problem. The idea is to get a general a fee...

Samba Team, We are trying to determine if the Samba version 2.2.8 will allow for NTLM V2 authentication. Could you please update me on what version of Samba allow for NTLM V2. Thank you in advance. Sam Martinez (303 236-1834) U.S. Geological Survey

...ce intervals in one direction only (up) as to avoid interference with any black and white shading. The plotMeans function provides a useful option error.bars ("se", "sd", "conf.int", "none"). The following test data is still useful: tmp <- expand.grid(geology = c("Sand","Clay","Silt","Rock"), species = c("ArisDiff","BracSera","CynDact","ElioMuti","EragCurS","EragPseu"), dist = seq(1,9,1) ) tmp$height <- rnorm(216) For instance plotting height v...

Just noticed that I get a similar error about object 'kronecker' in "Matrix" package when trying to load "lme4". So this is a more pervasive problem. Brian Brian S. Cade, PhD U. S.

I think I must be missing something obvious, but I'm having trouble getting a data transformation to work on groupings of data within a data frame (csss3) as defined by 2 factors (population, locid). The data are sorted by year within locid within population and I want to lag another variable (dbc), i.e, shift them down by 1 row replacing the first row with NA, within groups defined by

Hi, I would like to put the sample number beside each lable in a boxplot. How do I do this? Essentially, I need to count the sample size for each factor, see below: Thanks boxplot(DATA$K_Merge~factor(DATA$UnitName_1),axes=FALSE,col=colours) title(main=list("Tukey Boxplot by Geology:\n K(%)",cex=cexlb)) axis(1, 1:21, labels=FALSE, las=2) text(seq(1, 21, by=1), par("usr")[3], labels = levels(factor(DATA$UnitName_1)), srt = 45, adj = c(1.03,1.03), xpd = TRUE, cex=1.8) axis(2, seq(-1,5, 1), seq(-1, 5, 1)) -- Shane [[alternative HTML version deleted]]

hi- I have been using postscript()and contour() to do quick plots of geological sufaces and it would be handy to be able to dump a plot as an autocad dxf file for vector import into autocad. A search of rhelp of 99 thru 01 gave no matches for dxf. Any suggestions for a dxf or dump of a plot as vectors? Thanx Thanx Robert (Bob) L Sandefur Principal Geostatistician Pincock Allen & Holt

...in different habitats within sites which were within rivers themselves within different regions. The habitat correspond to different substrata (not systematically present in all sites). For rivers and sites, I have environemental variables (e.g. altitude and slope of the site, drainage area and geology of the river) and I have only 2 regions. Note that sometimes I have only one site per river. I would like to know the part of each spatial scale in the species richness variance. I looked into the nlme package but I did not found how to proceed... Thanks for your help Nicolas Poulet Laborato...

That is terminology from Computer Science. (Decades ago?) It is familiar. Not invented by Cisco. As in, producer-consumer, from the same time. Those were all different paradigms for client-server relationships. There must be Wikipedia citations that can be consulted. As I recall, there were distinctions, such as, producer-consumer were tightly bound, where the producer had no purpose
