Regex parameter in extract function in R - r

According to solution in Gather multiple sets of columns I am trying to gather multiple sets of columns. All columns which I would like to gather have year in the end of the sentece. column.name.2010, column.name.2011, column.name.2012, column.name2.2010, column.name2.2011, column.name2.2012 etc.
I tried
db %>%
gather(key, value, -c(1:6)) %>%
extract(key, c("question", "Year"), "([^\d{4}]+)") %>%
spread(question, value)
I would like to accomplish this:
Id Index.number Country.Name World.Rank.by.Assets Year column.name. column.name2.
1 a 3 6 2010 xxxx xxy
2 b 4 6 2011 xxyx xyy
3 c 5 8 2012 xxxs sada

To get std dev i did this
mat1 <- mat2
mat1[,-1] <- lapply(mat1[,-1],
function(x) replace(x,abs(scale(x))>2,NA))
The to find rows with any NA I did this
mat_rown <- mat1 %>% remove_rownames %>% column_to_rownames(var="Symbol")
which(is.na(mat_rown),arr.ind = TRUE)
Which gives me this data frame

here we can see these genes they have some or the other NA in different columns so my objective is to take out these rows .
So when Im trying to index those rows with NA
AACSP1,ABCA9-AS1,ABLIM1,ABO,ACOT12
I get these
row col
AACSP1 3 1
ABCA9-AS1 5 1
ABLIM1 7 1
ABO 9 1
AACSP1 3 2
ABCA9-AS1 5 2

So my simple idea is to preserve these NA containing rows or genes in another data frame or object which i can further use downstream for my different analysis to check

If you simply are trying to split your original frame into those that have a low vs high row standard deviation, you can do this:
rld2 <- as.data.frame((mat)) %>% rownames_to_column('gene')
# set your threshold that defines "high" deviation (i've picked a relatively low one here; you might choose something like 3)
sd_threshold = .6
# get the row-specific standard deviation, using `apply()`
row_sds = apply(rld2[,-1],1, \(r) sd(r))
# split into a list of two frames,
low_high_split <- split(rld2, f = row_sds>sd_threshold)

how to extract observation values for each cluster of Kmeans

I have data that come from two distribution functions (mixture data). I fit the k-means to the data with $2$ centers. I then get the clusters. My point here is, instead of the number of each cluster, I would like to divide my data into two groups. That is, the first group contains the data that comes from the first cluster and the same for the second group (my data is two dimensions and a matrix).
Here is my try:
kme <- kmeans(Sim, 2)
kme$cluster
which gives this:
kme$cluster
[1] 1 2 2 1 1 1 2 2 2 1 2 2 1 2 1 2 1 2 2 1 2 1 2 2 2 1 2 1 2 1 1 2 1 1 1 2 2 1 1 1 1 1 2 2 1 1 1 2 2 1 2 1 2 2 2
[56] 1 2 1 2 2 1 2 1 1 2 2 1 2 2 1 1 2 2 1 2 2 1 1 1 2 2 2 2 2 2 1 2 2 2 1 2 2 2 2 1 1 2 2 1 2
I know that means the first row (observations in the first row) of my matrix comes from the first cluster and the second and third rows are from the second cluster. Instead of this, I want two groups, one with the observations (the values not the number of the cluster) of the first cluster, and the other come from the second cluster.
For example,
[,1] [,2] [,3]
[1,] 0.8026952 0.8049413 1
[2,] 0.4333745 0.5063472 2
[3,] 0.3587946 0.4091627 2
[4,] 0.9067146 0.9211618 1
[5,] 0.6663730 0.6644439 1
[6,] 0.9752217 0.8299001 1
Hence, I want it like this:
Group_1
[,1] [,2]
[1,] 0.8026952 0.8049413
[2,] 0.9067146 0.9211618
[3,] 0.6663730 0.6644439
[4,] 0.9752217 0.8299001
Group_2
[2,] 0.4333745 0.5063472
[3,] 0.3587946 0.4091627

I hope this is what you are looking for.
I had to transform the matrix to a data frame so that when we use split function the structure will be preserved, otherwise it would split the whole matrix element by element as matrix is actually a vector that has dim attribute. So it behaves like a vector
split function divides a data frame or a vector into groups defined by f. which in your case are unique cluster values
kme <- kmeans(Sim, 2)
kme$cluster
Sim2 <- as.data.frame(cbind(Sim, kme$cluster))
split(Sim2, Sim2$V3) |>
setNames(paste("Group", sort(unique(kme$cluster))))

Add the kme$cluster values to the original dataframe and then create a new dataframe with each column based on the value in kme$cluster
From what I understand without a data sample:
library(tidyverse)
Sim <- Sim %>%
mutate(cluster_group = kme$cluster)
df_final <- data.frame(Group1 = Sim %>%
filter(cluster_group == 1) %>%
select(value) %>%
pull(),
Group2 = Sim %>%
filter(cluster_group== 2) %>%
select(value) %>%
pull())
With value the values used for the kmeans in Sim

R - Skip columns in pmax command if they do not exist

I'd like to use the pmax command to create a new column. My code Looks like this:
Master <- Master %>%
mutate(RAM = pmax(RAM1, RAM2, RAM3, RAM4, RAM5, RAM6, RAM7, RAM8, RAM9, RAM10,
RAM11, RAM12, RAM13, RAM14, RAM15, RAM16, RAM17, RAM18,
RAM19, RAM20, RAM21, RAM22, RAM23, RAM24, RAM25, RAM26,
RAM27, RAM28, RAM29, RAM30, RAM31, RAM32, RAM33, RAM34,
RAM35, RAM36, RAM37, RAM38, RAM39, RAM40, RAM41, RAM42,
RAM43, RAM44, RAM45, RAM46, RAM47, RAM48, RAM49, RAM50,
RAM51, RAM52, RAM53, RAM54, RAM55, RAM56, RAM57, RAM58,
RAM59, RAM60, RAM61, RAM62, RAM63, RAM64, RAM65, RAM66,
RAM67, RAM68, RAM69, RAM70, RAM71, RAM72, RAM73, RAM74,
RAM75, RAM76, RAM77, RAM78, RAM79, RAM80, RAM81, RAM82,
RAM83, RAM84, RAM85, RAM86, RAM87, RAM88, RAM89, RAM90,
RAM91, RAM92, na.rm =T))
In my current data base, however, only the columns RAM1 to RAM8 exist. In this case, I want R to skip all the other columns mentioned in the Statement and to only use column RAM1 to RAM8 (it is okay if R displays an error message, but I don't want the program to interrupt running the code).
Any ideas how to do so?
Thanks!

One way to do this would be as follows:
Set up some data to make a reproducible example
set.seed(0)
Master <- data.frame(Other=100,RAM1=1:10, RAM2=1:10, RAM3=1:10, RAM4=1:10,
RAM5=1:10, RAM6=1:10, RAM7=1:10, RAM8=rnorm(10)+5)
Master[5,5] <- NA
Select required columns of the dataframe:
Master[colnames(Master) %in% paste0("RAM",1:92)]
Use do.call to run pmax using the selected columns as arguments, and adding the argument na.rm=TRUE
Master$RAM <- do.call(pmax, c(Master[colnames(Master) %in% paste0("RAM",1:92)], na.rm=TRUE))
Sample output:
Master
# Other RAM1 RAM2 RAM3 RAM4 RAM5 RAM6 RAM7 RAM8 RAM
#1 100 1 1 1 1 1 1 1 6.262954 6.262954
#2 100 2 2 2 2 2 2 2 4.673767 4.673767

#4 100 4 4 4 4 4 4 4 6.272429 6.272429
#5 100 5 5 5 NA 5 5 5 5.414641 5.414641
#6 100 6 6 6 6 6 6 6 3.460050 6.000000

Extracting data from dataframe using different dataframe without headers (R)

I have a gridded data as a data-frame that has daily temperatures (in K) for 30 years. I need to extract data for days that matches another data-frame and keep the first and second columns (lon and lat).
Data example:
gridded data from which I need to remove days that do not match days in the second data (df2$Dates)
>head(Daily.df)

Second data I'm using for extracting (using Dates variable)
>head(df2)
Dates Temp Wind.S Wind.D
1 5/1/1991 18 4 238
2 5/2/1991 18 8 93

9 6/2/1991 21 8 192
10 6/7/1991 17 8 32
The header of the final data I'm looking for is something like this:
>head(df3)
lon lat 1991-05-01 1991-05-02 1991-05-04 1991-05-06 1991-05-09 1991-05-13

Example data following the format of yours
Daily.df <- data.frame(lon=1:5,lat=1:5,A=1:5,B=1:5,C=1:5,D=1:5)
colnames(Daily.df) <- c("lon","lat","1991-05-01","1991-05-02","1991-05-03","1991-05-04")
lon lat 1991-05-01 1991-05-02 1991-05-03 1991-05-04
1 1 1 1 1 1 1
2 2 2 2 2 2 2
3 3 3 3 3 3 3
4 4 4 4 4 4 4
5 5 5 5 5 5 5
df2 <- data.frame(Dates = c("5/1/1991","5/2/1991","5/4/1991"))
Dates
1 5/1/1991
2 5/2/1991
3 5/4/1991
Using lubridate to convert df2$Dates into the right format, make a vector of the column names you want to keep (thesedates) including lon and lat. Then use select_at to keep those columns.
library(lubridate)
library(dplyr)
thesedates <- c("lon","lat",as.character(mdy(df2$Dates)))
new.df <- Daily.df %>%
select_at(vars(thesedates))
Output
lon lat 1991-05-01 1991-05-02 1991-05-04
1 1 1 1 1 1
2 2 2 2 2 2
3 3 3 3 3 3
4 4 4 4 4 4
5 5 5 5 5 5

If you want to have a long data set to match, I would think you need to first convert the dates in df2 into the proper format and then wrangle the data into wide format.
Step 1 - Convert dates into correct format
df2$Dates <- as.Date(df2$Dates, format = "%m/%d/%Y")
Step 2 - convert to wide format
library(tidyr)
spread(df2, Dates, data)

extract rows with common characters in a column by comparing two data.frame

How can compare two data.frame (df1 and df2) and extract the rows with common gene names

When i tried
df2[mapply(function(x, y) length(intersect(x,y))>0,
strsplit(df1$Gene, ','), strsplit(df2$Gene, ',')),]
i got out

But i can find many rows with at least one common Gene

We could split up the "Genes" column in each datasets with strsplit, then compare the corresponding list elements with mapply, check if there is any intersect and use that index to subset the "df2"
df2[mapply(function(x,y) any(x %in% y),
strsplit(df1$Gene, ','), strsplit(df2$Gene, ",")),]
# chr start end Gene

#3 7180 9229 loss Sox1
#4 8159 8360 loss Sox1
#5 9154 10588 loss Pekg
Or use intersect and length
df2[mapply(function(x, y) length(intersect(x,y))>0,
strsplit(df1$Gene, ','), strsplit(df2$Gene, ',')),]
Update
If we need to find whether a single "Gene" of first dataset is found in any of the rows of second data (using the updated dataset)
df2[sapply(strsplit(df2$Gene, ','), function(x)
any(sapply(strsplit(df1$Gene, ','), function(y) any(x %in% y)))),]
