developing a package: increase the number of functions
Dear list,
I am trying to develop a package. I used the function package.skeleton to make the directory tree of the package and then build and compiled the package as described (I hope). Now, I would like to increase the number of functions in the package without overwriting the existing package directory tree, so I put these new functions in the directory R of the tree.

how to use the switch statement
Good morning,
I am trying to recode the values of a column in a data frame and,

Importing many files from a single code
Dear R users,
Does somebody know the way to import many files by a single command in R ? I have 50 files in a directory and now, i am importing the files repeatedly (one by one). If there is a way to import all files at a time, it makes much more easy and save times too.
Thanks in advance.

Statistical querry on Partial correlation test
Hi R users,
I want to calculate the partial correlation (first or second order) and their corresponding significance test (p-value).
I used

selecting significant predictors from ANOVA result
Dear all,
I did ANOVA for many response variables (Var1, Var2, ....Var75000), and i got the result of p-value like below. Now, I want to select those predictors, which have pvalue less than or equal to 0.05 for each response variable. For example, X1, X2, X3, X4, X5 and X6 in case of Var1, and similarly, X1, X2.......X5 in case of Var2, only X1 in case of Var3 and none of the predictors in case

Mathematical label in a plot with a percent sign

I am trying to produce a plot with an xlabel that reads (x >= 5%) with
