similar to: How to make truncated y axis (cut mark) in R plot?

Hi, I've plotted a Kaplan-Meier curve but the curves only range from 0.7 to 1 on the y-axis. Therefore I have used: - ylim=c(0.7,1) [although I think convention dictates that you plot 0.5 to 1 to show the median? A few papers I've read have done this]?? BUT, I would like a symbol like // (but rotated 90 degrees) to indicate that the y-axis has been truncated. I'd need to be able to

Dear All, I would like to fit some parametric survival models using left truncated, right censored data in R. However I am having problems finding a function to fit parametric survival models which can handle left truncated data. I have tested both the survreg function in package survival: fit1 <- survreg(Surv(start, stop, status) ~ X + Y + Z, data=data1) and the psm function in package

May I ask a clinical question? For a trial, we have a treatment group of small size, say 30 patients. We want to selectmatching control patients from a bigger group (100 patients) in terms of several clinical variables, such as age, tumor stage etc. This practice is to select the closest matching set of control cases. I wonder if R has any routine or package that can help with this problem.

Oh sorry. An example say lots more than words. The data below, when submitted to twoord.plot return the mentioned error. Rain are bars and Salt lines, the bars appear and the error occurs with the salt data.

R plotting experts: I have a bivariate dataset composed of 300 (x,y) continuous datapoints. 297 of these points are located within the y range of [0,10], while 2 are located at 20 and one at 55. No coding errors, real outliers. When plotting these data with a scatterplot, I obviously have a problem. If I plot the full dataset with ylim = c(0,55), then I cannot see the structure in the data in

Attached is a histogram chart with a break on y-axis which my friend made for me using phot shop. Do anyone know how to make such a break using R? Thanks in advance.

Hi folks, I want to have a y-axis using matplot where the y axis is truncated as shown schematically below: (msecs) 3000 | x ~ ~ 800 | x | | x | ----|----|----|----------------- 1 2 3 Position The ~ is supposed to stand for a curved line showing a break. The issue is that I want to plot the points shown by the

Hi, I have a data set with two continous variables that I want to plot MEANS (I am not intrerested in median values) on a double-y graph. I also have 2 factors. I want the factor combinations plotted in different panes. Dummy dataset: mydata <- data.frame(factor1 = factor(rep(LETTERS[1:3], each = 40)), factor2 = factor(rep(c(1:4), each = 10)), y1 =

Hi all, I read in a column which looks like "chr1:000889594-000889638", and need to break them into three columns like "chr1:", "000889594" and "000889638". How shall I do in R. Thanks a lot for your suggestions! Bill

Hi, I'm plotting a multiple histogram using the function multhist {package plotrix}, something like: library(plotrix) mh <- list(rnorm(200, mean=200, sd=50), rnorm(200, mean=250, sd=50)) multhist(mh) In this graph y-axis represents the frequency of observations.... but I would like it to be scaled into relative frequencies, does anybody know how to do this with multhist or similar

Hello all, I have been having trouble getting a break in my y-axis. All of my data points are up around 100-200, but the graph has to start at zero, so i would like to remove all the white space using a break symbol. I have been able to get the break and labels to be correct, however, I can't seem to get the data to match the axis anymore. I must be using the axis.break() in plotrix

Hi, I want to plot two variables on the same graph but with two y axis just like what you can do in Excel. I searched online that seems like you can not achieve that in ggplot. So is there anyway I can do it in a nice way in basic plot? Suppose my data looks like this: Weight Height Date 0.1 0.3 1 0.2 0.4 2 0.3 0.8 3 0.6 1

Dear R users, I encounter a problem regarding number of significant digits on y-axis. Below is my basic code: myplotkid<-xyplot(expected_offspringnumber~afr|decade,groups=SES,data1, auto.key=list(space="right"),layout=c(9,1),xlab="",ylab="Offspring number", aspect="fill",scales=list(x=list(draw=F)),strip=T) >From this code, you can see there are 9

R: how multiplying y-axis ticks value by 100 (without put the % symbol next to the number) here:? plot (CI.overall, curvlab=c("Discharge", "Death"), xlab="Days", las=1)? P.S. So instead 0.00, 0.20 etc. the 0, 20 etc. Thank you in advance, Nic [[alternative HTML version deleted]]

Hello, I have a question about the y-axis of plots. Actually I had about 60 values. About 80 percent of these values are less than 0.2, then the other 20 percent values are more than 4,max is 10. So when I plot these values together, the y-axis's range will go 0 to 10, and my major values (80% values <0.2) will be pressed around 0 on the bottom, while other several dots will scatter in

Basic question: I looked around quite a bit, still having a little trouble manipulating the distance between the Y-axis label and the plot. In this case, I would like to move the Y axis title closer to the plot. # Data tC <- textConnection(" Time Type1 Type2 Type3 1.3 .50 .10 .40 4.5 .45 .20 .35 5.2 .40 .30 .30 ") data1 <- read.table(header=TRUE, tC) data2 <-

I did not find an answer to my question after a quick search using the R search engine so thought I'd ask away: Does any know if there's a function exists to create an interrupted Y axis? What I mean by interrupted Y axis is that part of the Y axis has been removed or excised to permit one to see parts of the data in more detail. Perhaps an example will make this clear. Please go to
