I have so far used the following command glm(formula = s ~ age + gender + gemedu + gemhinc + es_gdppc + imf_pop + estbbo_m, family = binomial(link = "probit")) My question is 1. How do i discard the non significant selection variables (one out of the seven variables above is non-significant) and calculate the Inverse Mills Ratio of the significant variables 2. I need the inverse

I am typing the following on the command prompt: >variab = read.csv(file.choose(), header=T) >variab It lists 900,000 ( this is the total number of observations in "variab" ) minus 797124 observations and prompts the following message [ reached getOption("max.print") -- omitted 797124 entries ]] Is there a way to see the entire set of data, ie all of 900,000 obs, and

Dear R users I have a data set which has five variables. One depenedent variable y, and 4 Independent variables (education-level, householdincome, countrygdp and countrygdpsquare). The first two are data corresponding to the individual and the next two coorespond to the country to which the individual belongs to. My data set does not make this distinction between individual level and country

Hi, Is it possible to diagonally fill a rectangle with a color gradient? I noticed that the gradient.rect of plotrix could fill a rect either up and down or from side to side. I am looking for something similar but fills diagonally instead, e.g., from the upper left corner to the bottom right. Does anyone know how to do it in R? Thanks, -- Tom [[alternative HTML version deleted]]

Hello everyone, if I have: x=1:10 y=1:10 plot(x,y) and I plot a rectangle rect(4,0,6,11, col=5) it covers the points of the graph. Is there a way to draw the rectangle under the points? I was thinking the a solution could be draw an empty plot then draw the rectangle and after the points, but it did not work. Any idea? thanks for your help H. [[alternative HTML version deleted]]

Hi, I am trying to plot densities given on a two dimensional grid. My data is in the an external file, and is arranged in three columns: x, y, density how may i get a plot of this? i would like to get (1) a three dimensional plot and (2) a color coded two dimensional plot. I have tried using image(x, y, density) but i am asked to put the data in ascending order. i am not sure how i may

hi all, i am trying to make multi-color plots. that is, i generally use, plot(x, y, type="n") text(x, y, labels=class) here, the vector class denotes the class of each point. there are usually 3-4 classes of points. how may i display the different classes in different colors? thanks for any help. -- saurav

Hello fellow R users, I have a problem. I have created a barchart overlayed by an xyplot line, both of which read off the same Y axis. The problem comes when I try to generate a key. It seems that I can only create either two lines, or two rectangles. I would much prefer to have the barchat series depicted by a rectangle, and the xyplot series by a line. Is there a way to do this? Your help

Hi I am using Stata 10 and I need to import a data set in stata 10 to R, I have saved the dataset in lower versions of Stata as well by using saveold command in Stata. My RAM is 4gb and the stata file is 600MB, I am getting an error message which says : "Error: cannot allocate vector of size 3.4 Mb In addition: There were 50 or more warnings (use warnings() to see the first 50)" Thus

hi, i am need to plot two or more sets of data in a 3d scatterplot, each set with different color. i tried Rcmdr, and the 3d scatterplot facility, based on rgl. that is what i need. but i cannot seem to code different sets of data differently. any help will be very helpful. i tried scatterplot3d, but it is difficult to get the right angle in it. i need to be able to rotate the axes, and

I am trying to create a lattice plot and would like to later, i.e. after the plot is drawn, add a grey rectangle behind a portion of it. The following works except that the rectrangle is on top of and obscures a portion of the chart. I also tried adding col = "transparent" to the gpar list but that did not help -- I am on windows and perhaps the windows device does not support

How do I draw a rectangle across multiple plots on a device? E.g., def.par <- par(no.readonly = TRUE) par(mfrow = c(3, 1)) plot(1:10, rnorm(10), ylim = c(-4,4), type = "l") plot(1:10, rnorm(10), ylim = c(-4,4), type = "l") plot(1:10, rnorm(10), ylim = c(-4,4), type = "l") rect(2, -4, 3, 4) par(def.par) I want the rectangle to extend across the whole device. How

Hi I want to draw a rectangle behind a barplot such that it highlights those particular bars from the rest of the plot. I have figured out how to draw a barplot(), and then how to draw a rectangle of the correct shape and size (using rect()), but when I use rect() it draws over the top of the bars, and then when I re-draw the bars, it draws with a white background, thus eliminating my rectangle!

Hello anyone used to do similar things: search for the final C function that corresponding to the drawing of a rectangle? As listed in the subject, I started from heatmap() in R and after several steps reached the GRect() in C. However, then it refers to rect() which further seems to refer to do_rect(), and then, surpringly, do_rect refers to GRect()!!! A dependency circle! How can it work if no

Hi All, I am trying to use loess to smooth a 2D image, and also obtain the standard error for every pixel. I see that the standard error does not make sense. For example, running the following: library(stats) x <- array(c(1:100), dim=c(100,100)) y <- t(x) v <- exp(-((x-50)^2+(y-50)^2)/30^2) s <- v*0.02 g_noise <- rnorm(10000, mean = 0, sd = s) f <- v + g_noise f.loess <-

Hi there, I found one reference to add a reactangle behind a plot using plot(...,add=T), I tried this but didn't obtain the desired result. If a I have the following code: plot(x,y) rect(xleft, ybottom, xright,ytop,col='green) The rectangle appear on top of the plot. Any help will be greatly appreciated, Judith

Hi, I've been really struggling with this. If I have a vector like dat <- c(0,0,0,0,1,1,1,0,0,0,1,1,0,0,0,1,0,0,0) I want to plot each element as a colored rectangle (red=1, blue=1) in the right order, so they all stack up forming a vertical column on the graph. Sort of like a building, with each floor in the appropriate color. Any ideas? I've tried using ggplot and geom_tile, but my

Hi all, Is there a way to fill a rectangle or polygon with a color and/or transparency gradient? This would be extremely useful for me in terms of adding some additional information to some plots I'm making, especially if I could define the gradient on my own by putting functions into rgb something like rgb( r=f(x,y), g=f(x,y), b=f(x,y), alpha=f(x,y) ). Not so important whether the

Hi, For some reason I have been unable to use the predict function when I desire the standard error to be calculated too. For example, when I try the following: l<- loess(d~x+y, span=span, se=TRUE) p<- predict(l, se=TRUE) I get the following error message: Error in vector("double", length) : vector size cannot be NA In addition: Warning message: In N * M1 : NAs produced by
