similar to: abline(v= x) in plot with time formated xaxis not working

Good day all, I'm trying to plot a continuous line plot, which is followed by two forecast points eg. one forecast point is 12 months out, and another 24 months out from the last date of the line plot. In my attempts so far, the second plot (the forecast points) is scaled against a new axis scale, thus the two plots are not directly comparable (I need the forecast points to be scaled

Hi, I am new to R, and have a quick question regarding an R script that I received from a kind colleague. I am trying to determine the "peak" (maximum value) of the graph that is plotted when executing the following. There is an input file called "rates_values.txt" which begins as: rateValue 0.375693 0 1.71274 0 0 1.02832 0 0.16343 1.02349 0 0 1.47258 0.703522 0.390541

panel.lmline returns intercept and slope of y ~ x subsetted to the combination of conditioning factors given to xyplot in lattice. for instance: xyplot(Xvalues ~ log(Qvalues)|Tfac, data = df7, panel = panel.lmline) I am looking to find the equivalent formulation for lm() proper. If I do this: lmcal <- lm(Xvalues ~ log(Qvalues):Tfac, data = df7) Only one value of the intercept is returned.

Hi R list, I like the default ticks that are set up using grid.xaxis() or grid.yaxis() with no arguments. Finding good values for the 'at' argument is usually not a trivial task; the default behavior of these functions seems to work well. The problem with this strategy is that I cannot figure out how to "recover" the positions of these ticks when you do NOT specify the

Dear list, Can someone explain why the childNames below gives character(0) instead of the (canonical) names of the children grobs of the xaxis gTree ? [1] "major" "ticks" "labels" Many thanks in advance, Tobias ### minimal example code ### library(grid) pushViewport(plotViewport(c(5,4,4,2))) pushViewport(dataViewport(1:5, 1:5)) grid.points(1:5, 1:5)

>library(ggplot2) >(p<- qplot(mpg, wt, data=mtcars)) What I am doing is to set color of the ticks to hide them. >grid.gedit(gPath("xaxis", "ticks"), gp=gpar(col="white")) It should be a better way to achieve the purpose. Thanks.

Hi All, I try to do a scatterplot for a bunch of variables. I plot a dependent variable against a bunch of independent variables: -- cut -- graphics::plot( v01_r01 ~ v08_01_up11, data = dataset, xlab = "Dependent", ylab = "Independent #1" ) -- cut -- It is tedious to repeat the statement for all independent variables. Found an alternative, i.e. : -- cut -- mu

Hello there, I would like to plot a graph with the x axis's label displayed at a 45 angle to the x axis instead of horizontal to it as the label is very long. What should I do? Thank you for your help in advance Lisa Wang Princess Margaret Hospital Toronto, Ca

Hello, I have been trying to plot correctly a graph for 2 month now, with no success.I want to put a grid, adjusted on the X axis tickers. Here is the way I build my X-Axis and my grid: grid(11, NULL, col="grey40") axis(2) # build the tickers on the beginning of each monthticks.at <- seq(ISOdatetime(lastYear, 01, 01, hour=0, min=0, sec=0, tz="GMT"),

Hello, I'm making a simple plot using xYplot in the Hmisc library and having problems with labeling the values on the x-axis. Using the reproducible example below, how can I have the text (jan, feb,mar, etc.) in place of 1:12. Thanks, AB x <- c(seq(0,0.5,by=0.1),seq(0.5,0,by=-0.1)) ci <- rnorm(12,0,sd=0.1) xupper <- x + ci xlower <- x - ci mo.fac <- c("jan",

Dear All, Does anyone know how to get the maximum/minimum value of a function using R, I think there should be an instruction, but i can not find it in help files Thank you in advance for your help :) [[alternative HTML version deleted]]

I am new to R. I want to graph group data using a "Traditional Bar Chart with Standard Error Bar", like the kind shown here: http://samiam.colorado.edu/~mcclella/ftep/twoGroups/twoGroupGraphs.html Is there a simple way to do this? So far, I have only figured out how to plot the bars using barplot. testdata <- scan(, list(group=0,xbar=0,se=0)) 400 0.36038 0.02154 200 0.35927

Hi R-users! I'm trying to create an easy Excel chart using the package RDCOMClient.

Dear all, I am using the following code to write the plot to an eps format postscript(file="test.eps",horizontal=FALSE)

R-Help community, I understand that data.frames can hold elements of type double, string etc but NOT objects (such as a matrix etc). This is not convenient for me in the following situation. I have a function that takes 2 inputs and returns a vector: testfun <- function (x,y) seq(x,y,1) I have a data.frame defined as follows: testframe<-data.frame(xvalues=c(2,3),yvalues=c(4,5)) I would

Hello, I'm very new to R, and have managed to plot xy graphs, but can't seem to plot a matrix properly. The first column is my time points, and the following columns 2-4 are the replicates of my experiment. I've tried using row.names=1 to make the first column the value for that row (whereas before I had 1-31 sequence) and then my 1st column) but I can't work out how to tell it

Suppose I create an R program called myTest.R with only one line like the following: type <- as.integer(readline("input type (1: type1; 2: type2)? ")) Then I'd like to run myTest.R in batch mode by constructing an input file called answers.R with the following: source("myTest.R") 1 When I ran the following at the terminal: R CMD BATCH answer.R output.Rout it failed

Dear All: I have succeeded in fitting a GAMLSS.dist model to growth data I am working with it. My aim is to create a matrix of predicted percentiles and the corresponding the fitted model's sigma mu nu by agebins. Q: How do it generate these parameters as in L M S per Cole and Green 1992? Here are my working codes. Name of fitted model is gamlssfit > Agebin<-seq(6,36,6)
