How to split a DVD into multiple CDs

Question

This is my first post so hello everybody! I hope it will not be to nooby.

I have a problem of calculation Cochran Q-test for some of my data. I am receiving error that says:

Error in binom.test(length(signs[signs > 0]), length(signs[signs != 0]), : 'n' must be a positive integer >= 'x'

This code helps to see what is happening (part of my data here):

Data <- c(0, 0, 0, 1, 0, 0, 1, 1, 0, 1, 0, 0, 1, 1, 0, 0, 1, 1, 0, 1, 
      0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
      0, 0, 1, 0, 0, 0, 1, 1, 0, 1)

Data <- as.data.frame(matrix(data, 5, 10))

library(RVAideMemoire)
library(tidyr)
tData <- as.data.frame(t(Data))
colnames(tData) <- c(rep(1:5))
tData$id <- factor(row.names(tData))
tData %>% tidyr::gather(tree, count, c(1:5)) -> tData2
xy <- cochran.qtest(count ~ id | tree, data = tData2, alpha = 0.05)

But if I subset my data, then it works. Where is the problem?

data <- c(0, 0, 0, 1, 0, 0, 1, 1, 0, 1, 0, 0, 1, 1, 0, 0, 1, 1, 0, 1, 
      0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
      0, 0, 1, 0, 0, 0, 1, 1, 0, 1)

data <- as.data.frame(matrix(data, 5, 10))

library(RVAideMemoire)
library(tidyr)
tData <- as.data.frame(t(Data[1:4,]))
colnames(tData) <- c(rep(1:4))
tData$id <- factor(row.names(tData))
tData %>% tidyr::gather(tree, count, c(1:4)) -> tData2
xy <- cochran.qtest(count ~ id | tree, data = tData2, alpha = 0.05)

Solution 1

Instead of burning it into multiple CDs, why don't you use bootable USB with Windows 7 installation instead? Save your CDs and your time as well. I have wrote a blog post to make windows 7 installation from USB on my blog. You can read it here. Hope that can help you. Regards. Ivan.

Solution 2

Then you can't do it because the installer does not allow you to change disks during the install.

Alternatives:

• Buy/borrow a (USB) DVD-ROM
• Use a second computer or a LiveCD, format a partition on your harddisk as NTFS (version 6), set it as primary/active partition and copy the entire contents of the DVD into that partition. This should allow you to install from harddisk.
• If you have a Windows PE LiveCD, you can also start the installer directly from there.
• You can also try restoring the VHD/WIM image directly to disk, but it's actually a bit complicated.

i have already tried this, but my motherboard doesnt boot USBs.
