Hi All, I'm going to draw 8 plots in one page. I want the plots to be arranged in two rows, each row has 4 plots. So, I set the it par(mfrow=c(2,4)). However, there might be too many plots in a page, all the 8 plots were drawn in triangular shape, which makes the x-y coordinate scale not in same length, the x-axis length is much shorter than the y-axis length. Could anybody let me know how

Dear all, I have problem when reading a table into R. The total row of read in table has is much less than the original saved table. I built a 1,273,230 by 6 data set named "mydata2", it was saved in the following command, write.table(mydata2, "mydata2.txt", row.name=F,col.name=T,quote=F,sep="\t") The next day I read in above saved text file into R,

Hi all, I have a difficulty to calculate the PCA scores. The PCA scores I calculated doesn't match with the scores generated by R, mypca<-princomp(mymatrix, cor=T) myscore<-as.matrix(mymatrix)%*%as.matrix(mypca$loadings) Does anybody know how the mypca$scores were calculated? Is my formula not correct? Thanks a lot! Phoebe [[alternative HTML version deleted]]

Hi all, I have problem in ordering data frame. Could anyone help me? > x [,1] [,2] [,3] [1,] "A" "1" "2" [2,] "G" "3" "2" [3,] "E" "2" "3" > y [,1] [,2] [,3] [1,] "G" "3" "3" [2,] "A" "3" "3" [3,] "E"

Hi All, I am looking for help in rotating species titles produced using the strat.plot( ) function in the rioja package. This function produces a stratigraphic plot of paleoenvironmental data. Currently the titles of each species are plotted vertically while they are typically plotted at a 45 degree angle in other programs. Does anyone have any idea of how to rotates these titles? Below is an

Hi, I have been working through one of the examples on the FAQ about rotating the labels on the x axis, I need to do the same but for the y axis. I have managed to change some of the code, but I am still not getting there, there is still something wrong. My syntax is as follows: > par(mar = c(5, 7, 4, 2) + 0.1) > plot(1 : 8, yaxt = "n", ylab = "") > axis(2,

Hi friends, I have questions about printing a pretty big size matrix. As you could see from below, the matrix wasn't showed in R at full size (11X11), but it was cut partly into three smaller matrices (11X4,11X4,11X3). I'm wondering if there is a way to show the whole matrix with dimension 11X11, do you know how to make it? If R really couldn't fit the full big matrix at once, what

Hi all, I would like to construct plot of the distribution of N, where N range from 1 to 10. I couldn't just use the hist(), as I want the categories for the bars are: 1, 2, 3, 4, >=5. So this will be a bar plot with 5 bars, and the height of the bar will be the frequency of N. (eg bar#1 will be the frequency of N=1, bar #2 will be frequency of N=2, and bar#5 will be the frequency of

Hello Core Team, I sent this patch over a year ago. It looks like it was sent in response to another user's complaint which echoed some of my own observations about problems in the documentation for 'text'. Did anyone have a chance to look it over? I'd like to get it out of my queue. Thanks, Frederick On Tue, Apr 11, 2017 at 12:01:05PM -0700, frederik at ofb.net wrote: >
