Hi
First you shall move your folders to some other place than c:. Let say
c:\project\country\...
after that you can list folders by ?list.dirs and files by ?list.files.
you can then navigate directories by ?setwd, ?getwd and read files from them.
The exact code depends on what exactly you
Hey there guys.
I am having a question about Venn diagrams.
A colleague wrote a script based on the VennDiagram package a while ago,
that I was able to adapt for my data. I wanted a Venn for the soil bacterial
communities derived from forests of 4 different tree species.
It worked fine for me,
Obviously metafor and not metaphor.
Sorry

Can you please suggest.

I don't know how to do it in plyr but
xx - seq(1:300)
nn - trunc( length(xx)/4)
yy - xx[nn, ]
should come close. Have a look at ?ceiling or ?floor as an alternative to
trunc()

Hi,
There are lots of ways to do it in base R, but a long time ago I got
frustrated and wrote a crosstab function that did exactly what I
wanted:
library(ecodist)
mydata - data.frame(var1=c(0,0,1,1),var2=c(0,1,0,1),freq=c(11,12,13,14))
crosstab(var1, var2, freq, data=mydata)

As Sarah noted, there are a variety of ways in R to accomplish this, such as:

Yes and yes.
To be clear,
1. sum() is better.
2. xtabs is better (I just forgot about it and didn't bother to search).
Maybe the best answer is in fact,
??crosstabulation
which would have brought up xtabs(). So the moral is (to the OP),
learn how to search before posting.
Cheers,

If you insist on avoiding the stats package...
However, I'd use sum() rather than I() to get an xtabs() workalike.

Have you trying installing it directly from CRAN?
install.packages(lme4)
Do you have all dependencies installed? install.packages() from CRAN will
take care of that. You repos = NULL you have to install all dependencies

There are tolerances in the checks, and sometimes scaling of the problem
leads to false positives on the checks.
Try control = list(starttest=FALSE, etc.) to suppress the test.

I haven't tested this, but what about:
df - data.frame(mtch=c(matchString, string1, string2))
grep(searchString, df$mtch, ignore.case=FALSE)
Depending on what your next step is, you might prefer grepl.
Sometimes using fixed=TRUE in grep() helps.

+ is a special character in regular expressions that requires a preceding
pattern to apply to. See ?base::regex.
You need to escape the special with a backslash to remove the special behavior,
and escape the backslash so the R parser will be happy.
str_extract(+proj=utm +zone=19 +datum=WGS84
