tapply within a data.frame: a simpler alternative?
...e example below describes it best:
> x <- seq(0, 10, len=100)
> my.df <- data.frame(x = rep(x, 3), y=c(3*sin(x), 2*cos(x),
> cos(2*x)), # note how the y values have a different maximum
> depending on the group
> group = factor(rep(c("sin", "cos", "cos2"), each=100)))
> library(reshape)
> df.melt <- melt(my.df, id=c("x","group")) # make a long format
> df.melt <- df.melt[ order(df.melt$group) ,] # order the data.frame
> by the group factor
> df.melt$norm <- do.call(c, tapply(df.melt$value, df.mel...

...o start with I would like to make sure that I
got the output from (3) right. The ouput of (3) tells me that the highest
R^2 value was reached after 8 iterations and there are only 8 significant
predictors in this model ??? In addition the only significant frequencies
(predictors) left are:
cos1, cos2, cos4, cos7, sin1,sin2, sin3, sin5
I got this information interactively. But I'm in troubles at extracting it
automatically.
Any suggestion ?
Question: Do I have to run "step" in advance of "regsubsets" for a
first-pass model pruning or may I run "regsubsets" on...

Data consideration in executing pca
...g message:
Error in cor(nnotes) : 'x' must be numeric.
I eliminated the first column of names, then read the modified data and
then added the names of individuals with rownames. I was able to run PCA
and obtain graphical representations of the variables, their coordinates,
contributions and cos2. However, when I used fviz_pca_ind to get the
graphical representation of the individuals, I got a graphic that considers
the variables as individuals. Can you please help me? I have attached the
file data_1 .txt file.
Many thanks in advance.
