preparing data for barplot()
...barplot from my data? I would like
the barplot to show each person with the values stacked
val1+val2+val3, so there is one bar for each person When I use
barplot(data.matrix(realdata)), it shows one bar for each value
instead.
To post here, I created an artificical data set, but it works fine.
fakedata <- as.data.frame(list(LETTERS[1:3]))
colnames(fakedata) <- 'people'
fakedata['val1'] = abs(rnorm(3))
fakedata['val2'] = abs(rnorm(3))
fakedata['val3'] = abs(rnorm(3))
barplot(data.matrix(fakedata))
At a glance there is no substantial difference is between my f...

Help transforming a dist
I'd like to convert a dist into a table/matrix/thingy of the form:
A B value
A C value
B C value
(assuming the dist was over 3 names).
Is there a way to do this without using a for loop?

Parallelizing cor() for large data-set using Cluster
...I allocate 20000M and operate on 5 X 20000.
Even this is taking lot of time. Is there any way I can find
cl = cor(cdata) utilizing the computers in the clusters(I am using 32 nodes
).
I am using the following code to get the cluster..
library(snow)
cl <- makeCluster(64)
clusterExport(cl, "fakeData")
clusterEvalQ(cl, library(boot))
system.time(out2 <- clusterApplyLB(cl, pair, geneCor))
stopCluster(cl)
But here the geneCor and pair is calculated as,
pair <- combn(1:nrow(fakeData), 2, simplify = F)
geneCor <- function(x, gene = fakeData) { cor(t(gene[x[1], ]), t(gene[x[2],
])) }...

converting manual command to loop command
Dear useRs,
i have certain commands for some operations in R. They are good if you have a small dataset but my dataset, apart from what i used in the recent past, is prety large. I want to convert these massive sets of commands into a simple loop.
Your help is required on it
thanks in advance

kindly note:
"e" is matrix whose each column has to be executed into a distance vector

How to change the order of columns in a data frame?
Dear all,
I have a data frame in which the columns need to be ordered. The first column X is at the right position, but the remaining columns X1-Xn should be ordered like this: X1, X2, X3 etc instead of like below.
> colnames(pos1)
[1] "X" "X1" "X10" "X11" "X12" "X13" "X14" "X15" "X16"

remove multiple columns by name from dataframe
Hi there,
I'm trying to remove multiple columns by name from a data.frame. As a

"delete".

ANOVA plotting
Dear List,
I recently started using R and I have a simple question. I am running R (v.
2.12.1) and Rcmdr (v.1-6.3) on Mac (Snow Leopard).
I am using a data set I used before for practicing ANOVA with R, so I know
what the results should look like. I can get ANOVA table using both Rcmdr
and GUI. However, I cannot make R prepare the ANOVA diagram (with boxplots,
showing the data points, including

Time line plot in R?
Dear R users,
In order to illustrate the possible effects of events on variables
plotted against time, I would like plot a time line of events along side
the plot of the variables.
The x-axis should be some time unit; the y-axis should be the variable
of interest; the time line should be plotted below the graph along the
same x-axis scale.
As I have many variables and different events

Scaling values 0-255 -> -1 , 1 - how can this be done?
I have a dataframe in which I have values 0-255, I wish to transpose them such that:
if value > 127.5 value = 1
if value < 127.5 value = -1
I did something similar using the "binarize" function of the biclust package, this transforms my dataframe to 0 and 1 values, but I wish
to use -1 and 1 and looking for a way in R to do this.
