Hello everyone:
I have about a couple of thousands of samples each with about 100 SNP
genotypes and I would like to do PCA using genotypes. I looked on the
web and found different options available on R for PCA. I was
wondering if I could have advice about the program fits better what I
am trying
gument or used explicit values for ylim= in the first

Hello everyone:
I have 12 plots that I am using par(mfrow=c(3,2)) to have 6 of them in
a single page. R only prints the 6 first graph in a single page. Any
comments how I can ask R to print all 12 graphs in two pages.
Thanks very much,
Mohsen

Hello all:
I am having problem writing a few files in a single sheet of excel. It
seems R has problem writing on the same sheet. Maybe there is a command
that I am missing. Here is the code I am using:
library(xlsx)
ifn11 <- "A1.xlsx"
dat11 <- read.xlsx(ifn11, sheetName="A.csv", header = TRUE)
roblem is.

Hello:
I am reading some excel files (each with one sheet) and trying to write
them all in one file. I am not sure if read.xlsx reads some of the columns
as character or write.xlsx writes them as character where they are not
characters. I have 12 columns (2 character and 10 numbers). From 10 numbe

I have multiple CSV files that I would like to have them in a single Excel
file. For example, I have file1.csv and file2.csv and I want to have
file.xls where file1.csv and file2.csv each have been copied to a single
sheet of the file.xls file.
Thanks,

Hello All,
I am drawing a graph having 18 small graphs inside using par(mfrow = c(6,3))
command. My problem is how to specify the margins of the whole 18 graphs. I
used par(mar=c(6.5, 6.5, 1.5, 1.5)) for each graph separately already but it
does not left any margins for the 'mtext()' for the margi

Hello All:
If I do have:
x = (2, 4, 5, 5, 6, 4, 5, 2, 1)
y = (9, 11.5, 12.5, 13, 14, 19, 20, 21, 22)
I wanted to find a simple function in R which calculates the averages of X
and Y for every 4 unit increase of Y. The results should look like:
x = (4, 6, 3) #where (2+ 4+ 5+ 5)/ 4
Hello All:
Can somebody please tell me how I can have the average of 'y' on the graph
for different values of 'x in the following code?
ofn <- "xy.png"
bitmap(ofn, type = "png256", width = 21, height = 30, pointsize = 30, bg =
"white",res=50)
ifn <- sprintf("xy.txt")
