[R] lattice, latticeExtra: Adding moving averages to double y plot

Hi lattice users, I would like to add 5-year moving averages to my double y-plot. I have three factors needs to be plotted with moving averages in the same plot. One of these reads off y-axis 1 and two from y-axis 2. I have tried to use the rollmean function from the zoo-packages, but I fail in

[R] Differencing between 2 previous values

Hello All, I am trying to do a simple thing of calculating the absolute difference between 2 previous values. Since my original data consists of 30 rows, this column where I am storing my absolute difference values only consists of 29 rows (called the ?differ?)! And I am having troubling cbind

Re: [R] R and external C library " cannot open shared object file" while LD_LIBRARY_PATH is set

Thanks but that doesn't work: R cannot load a simple external library even if the full path to the directory is specified in the LD_LIBRARY_PATH. I posted a minimal example on gist.github: https://gist.github.com/lindenb/7cd766cbb37de01f6cce The simple C file is compiled but I'm not able to l

Re: [R] Function assignment

Thank you very much! The idea was to use it with an external reference and kind of to write an constructor for an object which points at this external reference and behaves like an R object. So it would be the same as if I do just name <- function("name", someValuesForObjectConstruction) but

Re: [R] Is there a package for EFA with multiple groups?

Hi Elizabeth, In confirmatory factor analysis with multiple groups, the reason one needs to estimate the models simultaneously is that, typically, one is interested in applying constraints (e.g., forcing all or some of the factor loadings to be equal across groups). In exploratory factor analysis

[R] using foumula to calculate a column in dataframe

Hello All, I need to calculate a column (Vupper) using a formula, but I am not sure how to. It will be easier to explain with an example. Again this is my dataset: dput(nd) structure(list(week = c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27,

[R] Calculate depth from regular xyz grid for any coordinate within the grid

Dear R-experts, I have a regular grid dataframe (here: the first 50 rows) : # data frame (regular grid) with x, y (UTM-coordinates) and z (depth) # x=UTM coordinates (easting, zone 32) # y=UTM coordinates (northing, zone 32) # z=river-depth (meters) df <- data.frame(x=c(3454240, 3454240, 3454240

Re: [R] Calculate depth from regular xyz grid for any coordinate within the grid

Hi, The area of statistics you're looking for is called geostatistics. There are many R packages to conduct such analyses. See the Spatial task view for some good starting points: http://cran.r-project.org/web/views/Spatial.html You'll need to do some homework to understand the various options a

Dear R-helpers, I've started the study of An introductionto applied multivariate analysis with R (Everitt and Hothorn) After loading the library, which depends on HSAUR2, it seems that the dataset "headsize" is not available (as well as "measure" and "exam") Datasets from the same book are neve

Re: [R] Function assignment

I am sorry but I don't follow your description beyond "use it with an external reference" because external references are external, while the destination of an assignment is an internal reference. If you want the destination to be an object which uses special knowledge (an external reference) to

Thank you very much Peter, Bill and Petr for some great and quite elegant solutions. There is a lot I can learn from these. Yes to your question Bill about the raw numbers, they are counts and they can not be negatives. The data is RNA Sequencing data where there are approximately 32,000 g

The raster package can readily provide bilinear interpolation: library(raster) r <- rasterFromXY(df) ## due diligence, just a guess here you should check ## projection(r) <- "+proj=utm +zone=32 +datum=WGS84" ## coordinates to extract m <- matrix(c( 3454263, 5970687), ncol = 2) extract(r, m, meth

It will be difficult to help since all of the attached files were stripped out of your message. R-help accepts very few formats as attached files and they do not include .R or .csv or .xlsx, but they do include .txt (so you could rename your R and csv files). It will be easier to help if we have

Hi Above what David said, there is chance that you do not need cycle for your computation. From what you describe about your csv files there seems to be some mismatch in your write.csv statement. Make a small example code together with data set, preferably as an output from dput, and try agai
