use list elements to subtract values from the dataframe
Hi,
I have a dataframe wf existing of a header with different labels and beneath
the values of those labels :
wf:
label1 label2 ...
0,45 0,21
0,10 0,45
.... ....
I have a list
fl <- c("label2","label3",..)
Isn't possible to use the list elements in the list in order to subtract
values from the dataframe? like :
wf$fl[[1]]
When I do in R I get :NULL

select rows from data based on a vector of char strings
Hi,
I have loaded a dataset in R :
data =
label freq1 freq2
news 54 35
fun 37 21
milk 19 7
food 3 3
.... etc
And I have a vector
flist<-c("fun","food")
Now I want to use the vector 'flist' for selecting these values from 'data'
so that I get the following dataset :
label freq1 freq2
fun 37 21
food

join chars in loops
Hi,
Is it possible to create new vars in a loop
For instance:
for (i in 1:11)
var'i' <- assign something
output =
var1
var2
...
var11
Is there a way to combine/join the value of 'i' to the string/char var in de
loop.

What are ties? Wilcox u-test
Hi,
When I execute a Wilcox u-test on two variables I receive a warning :
'cannot compute exact p-value with ties'
- What are ties? What does this mean for my data?
- Is that a problem for significance testing?
- is there a way to overcome this problem?
I have different threads in this forum but it hard to find what the exact
meaning of this warning message is.

multiple plots over multiple pages
Hi,
I would like to iterate over a dataframe and plot several graphs over
several pages. For instance, an iteration over the dataframe will result in
20 plots. Since 20 plots in one page is too much (too many small plots) I
would like to distribute them over 5 pages with each 4 plots.
I know how to create multiple plots on one page with :
par(mfrow=c(2,2))
