Ok thats in my opinion a little workaround
why?:
There is an
= and !=
< and >
means the opposite is available between terms.
why is there f.e no %!in%, %notin% or !%in%
This would be more intuitive.
Kind regards Knut
Thank you Bert and Peter. My apology for posting poor code. I cannot
create a reproducible example of my data, but i hope the list indices
as shown below helps you understand my question.. My regex pattern on
my previous post works correctly because i tested it on a few sublists
and it worked, but
If your matrices are at various depths in the list, try rapply(). E.g.,
> L <- list( A = list( a1 = matrix(c("AAA","AB", "AAB","AC"),2,2),
a2=c("AAx")), list(B = c("AAb1AAA","AAb2")))
> str(L)
List of 2
$ A:List of 2
..$ a1: chr [1:2, 1:2] "AAA" "AB" "AAB" "AC"
..$ a2: chr "AAx"
$ :List o

There's not much we can do with a text printout (at least without some work
that I don't care to do).
2. Do you know what mylist[[c(1,2,1)]] means? If not, read ?(Extract) and
note in particular:

You should be more specific about what you want to replace and with
what. The pattern you use, namely "[0-9][0-9]/[0-9[0-9].*com", does
not (AFAICS) match any of the strings in your data, so don't be
surprised that your commands do not change anything.
If you have a correct pattern and replacement
Hi All—
I have a list that contains multiple sub-lists and each sub-list
contains multiple sub(sub-lists), each of the sub(sub-lists) is made
up of matrices of text. I want to replace some of the text in some
parts in the matrices on the list. I tried gsub and stringr,
str_remove, but nothing see

Hi Bert,
another question for indexing
1. is there a good manual for indexing
2. is it possible to get !%in%
f.e
x =data.frame("A"=c(1:5),"C"=c("A","B","C","D","E"))
y =data.frame("B"=c(1,3,5))
test = x[x$A %in% y$B,]
test = x[x$A %in% y$B,]
test
