question about binary data file and data.frame
I have a binary file with data sequence in the order [age,weight][age,weight] .... I know the length of the data and I want to load it into a data.frame. of course a way to do this is to read age and weight seperately and then use cbin(age,weight) to combine them into a dataframe, but is there a better solution? Thanks in advance!

Reliability of samba
When I mount samba partitions using smbmount on a Linux box under /mnt/linnet_g and run this command: find /mnt/linnet_g/ -type f|xargs wc I get a number of errors which look like this: wc: /mnt/linnet_g/analysis.lesion/b19o61/b61o19.9/b61o18.9-042303.332.cbin: Input/output error What does this mean? The error is repeatable in a I am using samba-3.0.14a-6 on a Debian machine, with kernel 2.6.8. How does smbclient handle the type of errors which produce these results? I have seen a few explanations, but I can't find a really good answer. Perhap...

Problems when using lag() in plm package
...inding to the original data frame, with missing values at the correct locations. The names() for the lagged series are incorrect, but I don't really care about them. So this is basically the behavior I had hoped to see. However, if year 4 is not present in unit2, the gap is not detected. A cbind() with the original series is now incorrect data, although the names() of the lagged series could now be interpreted as correct in the strictest sense. However, if this is the expected behavior, that means that all estimation functions will have to examine the names() of each series, which see...

Analyzing "Stacked" Time Series
...<- arima(X, order = c(1, 0, 0)) fit.gls001 <- gls(X ~ YO + YD + ZO + ZD, correlation = corARMA(p = 2), method = "ML") fit.gls002 <- gls(X ~ YO + YD + ZO + ZD + lag(YO) + lag(YD) + lag(ZO) + lag(ZD), correlation = corARMA(p = 1), method = "ML") ar001 <- ar.ols(cbin(X, YO, YD, ZO, ZD)) Here is my example: xAB <- as.ts(round(rnorm(10, 0, 1), 2), start = c(1990, 1)) xAC <- as.ts(round(rnorm(10, 0, 1), 2), start = c(1990, 1)) xBA <- as.ts(round(rnorm(10, .75, 1.5), 2), start = c(1990, 1)) xBC <- as.ts(round(rnorm(10, .25, 1.9), 2), start = c(1990, 1...

cbind is not generic as claimed, omits labels where S has them (PR#239)
(1) ?cbind claims The generic functions `cbind' and `rbind' take a sequence of vector and/or matrix arguments and combine them as the columns or rows, respectively, of a matrix. Note: The method dispatching is not done via `UseMethod(..)', but by C-internal dispatching...

Help me apply mapply
...nd sr is a matrix. I would like to call many times the findCell function (thus I need mapply) for different x inputs but always for the same sr. as x is a vector of size two (two cells) I want to pass inside inside the following 2*10 matrix. -The first input is the two elements of the first row cbin(test[1,1],test[1,2]) -the second input is cbind(test[2,1],test[2,2] -the third input is cbind(test[3,1],test[3,2] and so on This is the str: str(cbind(test[,1],test[,2])) num [1:30, 1:2] -1 -0.667 -0.333 0 0.333 ... so I tried the following: > mapply(findCell,x=cbind(test[,1],test[,2]),sr=sr...
