Dear R-experts,
I am relatively new to R. Please help me in converting a dataframe into a
numeric and then creating a new dataframe.
R-code attached:
my_xtrain=read.table(./train/X_train.txt)
my_xtest=read.table(./test/X_test.txt)
my_merge_data=merge(my_xtrain,my_xtest,all=TRUE)

Hello everybody. I am not sure if I am in the right forum for my question. If
so, please let me know so I can go somewhere else! Thanks. Currently I am
trying to familiarize myself with R. I am trying to plot some sort of Network
graph (think of migration maps). Basically, I'd like to have an
Dear Subscribers,
how is it possible that the loadings of the second or even third
component of a PLS-Analysis show higher values than the first component?
Somebody got an idea??
Thanks in advance,
Wolfgang

Dear Mr. Jim Lemon,
I tried to contact you via e-mail, but apparently it didn't work.
I enjoy using the function corner.label() a lot, since I tend to use multiplots.
However, recently I discovered two issues:
firstly, the parameter cex doesn't work; for this I was able to produce a
simple

Hello list,
I recently started working with the step() function in the lmerTest package and
I notice a weird behavior that may be a bug. The package perform stepwise
selection of fixed and random effects, however when it discard the random
variable because not significant, it changes the
Dear All,
I am trying to fit the following model in nlsLM():
fn5 - function(x, T, t1, w_inf, Lt0){
S-function(x, T, t1){
x+(1-T)/(2*pi)*sin(2*pi*(x-t1)/(1-T))
}
F - function(x, T, t1){
t2 - t1 + (1-T)/2
t3 - t1 + (1+T)/2
t.factorial - x%%1
floor(x)*(1-T) + S(t.factorial, T, t1)*(0=t.factorial
Suitable help may not be possible. I suspect that either your
function/code is funky (is the function smooth, non-infinite near your
starting value?) or you are overparameterized. If the latter, the
remedy may depend on the nature of your data, which you have not
shared.
While you may receive
I was trying to ask if there is way to change the color of the axis...
Thanks!

Hi, Dr. Gu,
Thank you very much for the answer. This trick works.
Another question, is there a way to change the color or the axis?
Thanks!

Hi there,
I'm performing some propensity score matching in R, where I am using
GenMatch() to generate a weight matrix for the covariates, before plugging
that into Match(). However, I keep on getting different results each time I
run the code. I'm using int.seed and unif.seed in GenMatch, but to
Dear List,
I hope this posting is not redundant. I have several list outputs with the
same components. I ran a function with three different scenarios below
(e.g., scen1, scen2, and scen3,...,scenN). I would like to extract the
same components and group them as a data frame. For example,
Something like
scens - paste0(scen, 1:N)
new.df - data.frame(sapply(scens, function(x) get(x)[[pop.inf.r]]))

You are chasing ghosts of performance past, Denes. The data.frame
function causes no problems, and if it is used then the OP would not need
to presume they know the internal structure of the data frame.
See below. (I am using R3.1.2.)
a1 - list(x = rnorm(1e6), y = rnorm(1e6))
a2 - list(x =
Dear R.
My name is Darwin, I'm currently doing my thesis and I want to develop a
package to help me predict georeferenced data, ie whether there is any
pattern or behavior to know if it will happen again the same event again, I
might say statistical technique helps to accomplish what I need or
I have the following cost function:
cost-function(x){
x[,1]*sin(4*x[,1])+1.1*x[,2]*sin(2*x[,2])
}
If I send in a matrix which has MORE than one row and 2 columns, this
works fine. However, if I try to do cost(t(as.matrix(c(1,1 it
gives me an index error. When I tried debugging it, I found
Hi
I can not reproduce your error
