I have been trying to read in a large data set using read.table, but I've only been able to grab the first 50,871 rows of the total 122,269 rows. > f <- read.table("http://www.cs.odu.edu/~fmccown/R/Tchange_rates_crawled.dat", header=TRUE, nrows=123000, comment.char="", sep="\t") > length(f$change_rate) [1] 50871 From searching the email archives, I believe this is due to size limits of a data frame. So... 1) Why doesn't read.table give a p...

I have a power law plot in log-log scale using plot(x,y,log="xy") but I can't get the regression line to plot correctly. abline(lm(log(y)~log(x))) plots a straight line that looks promising but the intercept with the y-axis seems to be way off. summary(lm(log(y)~log(x))) gives the values but i cant really make any sense out of it. fitted(..) just confirms the values that seem to be

Attached is a histogram chart with a break on y-axis which my friend made for me using phot shop. Do anyone know how to make such a break using R? Thanks in advance.

...I made a fe more tests and the number of residuals which appear (to me) miss-calculated gets larger and larger when I test q>1.

...ot function. I understand how to change the color of the border (border="white"), but I need the border to be invisible so I can plot many skinny bars right next to each other with only the bar's color visible.

My stat textbook tells me that using Shapiro-Wilk test for each variable one by one is not equal to a test for multivariate normality as a whole. Does R have a function of testing for multivariate normality? Thanks.

Hi All I don't know whether i am asking on a correct list or not i have a query that how to know that what system call are called when packet enters the system or when we send a packet from a system? Thanks

I am trying to fit a logistic model to my 10 year data (1999-2008) by year. Codes like below: Year <- c(1999: 2008) for(y in 1:length(year)) { file.input <- paste("C:\\", year[y], "\\data.csv", sep="") table <- read.csv(file=fileinput, header=TRUE, as.is=TRUE, na.strings=c("")) initial <- getInitial(percent ~ SSlogis(age, Asym,

This seems like a very basic question so I have searched the FAQ site, several manuals, and the R-Seek site as well as Googling for an answer but can't seem to come up with one. I am trying to import an Excel file that resides on a University network. The path name of the file is to a network drive and includes blank spaces (e.g. K:/science/next directory science2/mydata/). The setwd() works

w.age.female.2004 <- nls(WEIGHT ~ (alpha*TOTAL^beta)/454, start=list(alpha=1, beta=3), data=spottedseatrout2004.female.data) I am trying to fit above model to length-weight data of a fish species (spotted seatrout) by year (1999-2006). The convergence occurred for all the years except 2002 and 2004. In these two year, R shows the error called
