hi everyone, i am having difficulties with replacing the dates format in R for exporting the data set... eg: the code that i used was toms_dat<- replace(toms_dat, toms_dat ==2009-08-06, 2) toms_dat<- replace(toms_dat, toms_dat ==2009-08-04, 1) but when i export the data as into txt file or excel file the dates come up with very large numbers .....:drunk: please help me ...=) -- View

Hello dear R-help members, Very soon I am to give a lecture on R. And in that lecture I intend to move between: par(mfrow = c(1,1)) to par(mfrow = c(1,2)) back and forth. I anticipate this will damage the image proportions and will force me to resize the window. So far I have found it is possible to close the window and then reopen it (bigger/smaller) by using: dev.off()dev.new(width=5,

Dear members, I would like to pass the histogram settings to each subset of the dataframe, and generate a multiple figures graph. First, can anyone tell me how to generate a multiple figures environment? I am trying mfrow=c(2,4) and nothing appears. Secondly, I want to pass the following function in tapply() hist(x, freq=FALSE) lines(density(x), col="red") rug(x) how can I manage

I am new to R and have a problem that I haven't been able to find the answer to in the guides or online. I have multiple datasets, D1, D2, D3, D4, D5, D6, D7 and D8, and I would like to produce two plots side by side using mfrow.  The first plot should contain data from D1-D4, the second should contain D5-D8. I can plot these separately using the code, par(mfrow=c(1,1))

Hi everyone! I have this dataframe: firm<-c(rep(1,4),rep(2,4),rep(3,4),rep(4,4),rep(5,4),rep(6,4)) year<-c(rep(2000:2003,6)) industry<-c(rep(10,4),rep(20,4),rep(30,4),rep(10,4),rep(20,4),rep(30,4)) X1<-c(10,14,18,16,20,45,23,54,24,67,98,58,16,32,57,12,54,0,0,22,11,3,5,6) data<-data.frame(firm, industry,year,X1) data I need a loop that calculates the mean of X1 by year and by

Hello all, The following line of code includes a right-to-left language text, yet the R graphics engine displays it from left to right. One problem this causes is when there are parenthesis in the test, here is a basic example? plot(1:10, main = "שלום (טקסט)") Is there a way to make sure the text is displayed from right to left? Many thanks for any suggestions, Tal

Dear R-users I have a problem choosing initial points for the function arms() in the package HI I intend to implement a Gibbs sampler and one of my conditional distributions is nonstandard and not logconcave. Therefore I'd like to use arms. But there seem to be a strong influence of the initial point y.start. To show the effect I constructed a demonstration example. It is reproducible

Dear list, I'm running windows xp with R 2.12.0. I'm trying to load a excel spreadsheet into R using the xlsx package.

Hi, I'm using the hist function to plot the frequency of 21 variables, but it keeps starting the x-axis from 0 and adding variables 1 and 2 together (all other vairables have the correct frequencies). I suspect it adds 1 and 2 together so that 0 can fit in with demarcations at intervals of 5. Using "xlim=c(1,21)" to specify that i don't want to include 0 and using the

Hi all, I'm trying to generate a grid of four plots. The first 2 appear just fine, but the final 2 will not appear in the grid, instead overwriting the first two. Any ideas on how to get them all in the same window would be greatly appreciated. Cheers, Jonathan library(fields) par(mfrow=c(2,2)) #2x2 plot windows plot(c(2,4),c(2,2)) # works fine plot(c(2,4),c(2,2)) # works fine

Dear all, I am trying to plot 3 histograms on the same graph using the following command. hist(x,xlim=c(0,100)) hist(y,add=TRUE) hist(z,add=TRUE) The xlim of y is c(20,21) and that of z is c(99,99.5) , whereas the variable x has xlim at c(0.5,2). Apparently, the graph end of displaying a line only, corresponding to each histogram due to the wide range of the xlim and tightness of the

I would like to know if you have any suggestions how to visualize the results from a paired t-test (see the example data below). I tried to produce plots that show the mean and CI's from the original data and the estimate of the difference between means and the confidence intervals (see below) from the t-test. I really don't know what would be the best way to graphically display the

Hi I'm a relative newbie to R and had a query concerning plotting. I have generated a par(mfrow = c(2, 2)) graphic with 10 rose diagrams using circular. What I wanted to add to each individual plot was "n = x" for the number of data observations in each dataset. How might I go about doing this?? Thanks Mike -- View this message in context:

Any idea why I can no longer plot two graphs on the same graphics device using the par(fig=) parameter? A simpler par(mfrow=c(1,2)) does work, showing the two plots side-by-side, but I would like the first to be larger. This simple example fails: x<-c(1,1,NA,2,2,NA,3,3) y<-c(2,4,NA,3,5,NA,1,4) par(fig=c(0,2/3,0,1)) plot(x,y) par(fig=c(2/3,1,0,1)) qqnorm(x) When plotted, the last

Dear List, This is just a programming problem which i cannot seem to figure out.

I am trying to reduce to pain of writing the whole set of data points (p# below) using "for" loop. However, I seem to have some problem in it as the output "M" does not
