The write.csv() function is currently implemented as function (..., col.names=NA, sep=",", qmethod="double") { write.table(..., col.names=NA, sep=",", qmethod="double") } Surely, it should be function (..., col.names=NA, sep=",", qmethod="double") { write.table(..., col.names=col.names, sep=sep, qmethod=qmethod) } so t...

Hello all, I had some trouble recently with write.csv because I couldn't change one of the default options. A quick view of the code showed that the function was not defined in the most optimal way. Currently, write.csv <- function (..., col.names = NA, sep = ",", qmethod = "double") write.table(..., col.names = NA, sep = ",", qmethod = "double") Thus, the options passed along to write.csv are ignored by the function (unless in the ...). Perhaps a better way to define the function is as such (similar to read.csv): write.csv <- f...

df <- data.frame(a = "a\"b") write.table(df, "test.csv", sep = ",", row = F) Is there any to load test.csv into R correctly? I've tried the following: > read.table("test.csv", sep = ",") [1] V1 <0 rows> (or 0-length row.names) Warning message: In read.table("test.csv", sep = ",") : incomplete final line

Full_Name: Kingsley Oteng-Amoako Version: 2.5.1 OS: Windows 5.1.2600 (Windows XP) Submission from: (NULL) (203.185.215.144) The col.names=false in the write.csv command does not work as documented. Attempting to write a vector to a csv file without column headers does not work as documented. The col.names=false feature on the write.table command does however work and it can thus be coerced

Last week one of our clients reported trouble with a csv file I generated with write.table. He said that columns with quotes for character variables were rejected by their data importer, which was revised to match the way Microsoft Excel uses quotation marks in character variables. I explained to them that quoted character variables are virtuous and wise, of course, but they say Microsoft Excel

...################ I get: The MAX3 test using the asy method data: a statistic = 0.5993, p-value = 0.7933 How can one save the result 0.7933 into a file? say: foo <- 0.7933 write.table(foo, file ="/home/foo.txt", sep = " ", row.names=FALSE,col.names=TRUE, quote=FALSE, qmethod = "double") However, instead of typing the value above, I would like to replace it by the macro (scalar, local) that has the accurate p-value. thanks in advance for your help.
