Can't Load Text Files
...o text. I don't know if it's
relevant, but I use a mac.
These are the error messages I get:

Error in eval.with.vis(expr, envir, enclos) : object "Date" not found
Error in source("/Users/jiayingmei/Desktop/R/Testinput.txt") :

I'm sure its something simple that is causing this, but I've been away
from R very long, and I've been trying to pick it up today, sorry if
this is a stupid post. I even tried to shift th...

Can R fill in missing values?
...are filled with NAs (which is what the all.x=TRUE does).
Is there any way to replace those NAs with the value of the latest row
that contains a value?
For example:
> Date<-read.table("Desktop/R/Testdate.txt", head=T, sep="\t")
> Data<-read.table("Desktop/R/Testinput.txt", head=T, sep="\t")
> Merged<-merge(Date, Data, all.x=TRUE)
> Merged

Activation Functions in Package Neural
...rainInput <- matrix(rnorm(10))
trainAnswers <- ifelse(trainInput <0, -1, 1)
trainNeurons <- 1
trainingData <- mlptrain(inp=trainInput, neurons=trainNeurons,
out=trainAnswers, it=1000)
## To call this network, we can see how it works on a set of known positive
and negative values
testInput <- matrix(-2:2)
mlp(testInput, trainingData$weight, trainingData$dist, trainingData$neurons,
trainingData$actfns)
Will vary - but output on my computer was:

[1,] 0.001043291
[2,] 0.001045842
[3,] 0.072451270
[4,] 0.950744548
[5,] 0.950931168
So it's instead classifying the...

I have been given data files in the following configuration and have
been puzzling about how to read them in. First I will give a snippet

Skipping lines and incomplete rows
I have a text file that has semi-colon separated values. The table is nearly
10,000 by 585. The files looks as follows:

First line: Skip this line
Second line: skip this line
Third line: skip this line
