Hello dear members of R-help and R-core mailing list, I am not sure if this request is a "ticket" that should be filled somewhere outside the mailing list. If so, I apologize for not doing and would like to know where I should have filled it. And to the subject matter: I would like to use a command like this: plot(c(1,8), 1:2, type="n") polygon(1:7, c(2,1,2,NA,2,1,2),

Hello everyone, If I want to convert or combine a (large) character matrix into a data frame without having any of its columns convert into a factor class, is there a simple solution? I() says it will operate on 'an object' but it seems that unless the object is a vector, the results are not what I expect. For instance, if g is a 2x2 character matrix, as.data.frame(I(g)) will return an

Hello, I am trying to switch to R from S-PLUS 6.1, and one problem I am having is using R for manipulation of calendar-based time-series. In S-PLUS, I commonly use the functions timeSequence(), timeDate(), and timeSeries() to align/average/aggregate data; and I also do a lot of plotting of time-series data (with calendar-based labels on the x-axis). I was wondering if anyone is familiar with

Dear all, I'm new user of R package. I'm trying to interpolate climate variables from ERA data. Original data contains 6 column with 29,040 lines, and x, y dimension are 240x121. I would like to get new data from column name: "lon", "lat" and "temp" by x, y dimension are 3,586x1,800 So I used the code as below, but I got error message as "z[cbind(lx1

Hi, I am having an issue when creating a postscript file from RGL window. It seems to cut off some of the axis labels. Here is the code I am using. I created a 3D plot using RGL_0.71 with R 2.5 on Windows XP. z1<-c(5,4,1,4.5,2,3,2,1,1) z2<-c(6,8,7,7.5,5,3.5,4,1,1) z3<-c(3,2,4,7,3,4.5,6,2,3) x1<-seq(1,9) x2<-seq(1,9) x3<-seq(10,18) y1<-seq(8,0) y2<--1*y1

I wanted a simple function for bilinear interpolation on a 2-D grid, and interp.surface() in the fields package didn't quite suit my needs. In particular, it requires uniform spacing between grid points. It also didn't have the "visual" reference frame I was looking for. Here is an alternative function, followed by an example. # A function for bilinear interpolation on a 2-d

I can run one-sample t-test on an array, for example a matrix myData1, with the following apply(myData1, 2, t.test) Is there a similar fashion using apply() or something else to run 2-sample t-test with datasets from two groups, myData1 and myData2, without looping? TIA, Gang

Hi How can I do the same has interp in s+ with R ? I've looked to "approxfun" but didn't figured out how to do it.

Dear all I have this table > dput(mat) mat <- structure(c(2, 16, 9, 2, 16, 1, 1, 4, 7, 7, 44.52, 42.8, 43.54, 40.26, 40.09), dim = c(5L, 3L)) And I want to calculate result for contour or image plots as I did few years ago. However interp does not compute the z values and gives me zeros in z matrix. library(akima) > interp(mat[,1], mat[,2], mat[, 3], nx=5, ny=5) $x [1] 2.0 5.5

Dear List, I'm using interp() to prepare 3d data for plotting with the contour() function. If have x,y and z data. All are arrays. X and Y are sampled in an orderly fashion on a grid (a circular sub-area of a grid - see plot). I'm trying to use interp() to get x and y arrays and a z matrix that can be fed to contour(). This is the command:

Dear R users, I want to do a fitted.contour plot of selected columns of a dataframe M with M$AM and M$Irradiance as x and y axes respectively. The level of the contour shall be determined by M$PR. Some words on my data first. Dataframe M looks like: head(M$Irradiance) [1] 293 350 412 419 477 509 head(M$AM) [1] 2.407 2.161 1.964 1.805 1.673 1.563 head(M$PR) [1] 70.102 72.600 75.097 80.167

The akima package has a problematic license (it doesn't allow commercial use), so it's been recommended that people use the interp package instead. When I use interp::interp instead of akima::interp, I get reasonable output from your example. So that's another reason to drop akima...

Hi I'm looking to a function in R equivalent to S-PLUS' "interp". Is there any implementation in R? If not, is there any similar interpolation function such that at the data points the interpolated values concides with the data? Thanks in advance P.J.

Dear R-users, I build already many contour graphs using the contour-procedure in R (akima library), after interpollating my data z on x,y (see e.g. graphs in this paper: http://www.biomedcentral.com/content/pdf/1471-2148-9-16.pdf). Now, however, i experience unexpected and completely unsensible problems: after building the syntax, i can create the graphs and use the interp-command without any

I am trying to establish a domain trust between a Samba 3.024 domain and a PC Netlink 2.0 domain. Currently, we are using PC Netlink as our primary Windows file server and "NT4" domain controller. (Lets say that the domain is called LEGACY and the domain controller LX1) Windows 2003 servers are unable to join a PC Netlink domain (even with the SignOrSeal option disabled.) For

Although it seems to be pretty weird to enter a numeric vector of length one that is not an integer as the first argument to sample(), the results do not seem to match what is documented in the manual. In addition, the results below do not support the use of round rather than truncate in the documentation. Consider the code below. The first sentence in the details section says: "If x has
