I try to select just one row in my data but the result come out in new data and I can't compute the mean of this, because the header is showing. But when I select the column, there is no problem and I can see the result as a value. You can see the result of the code in the photo that y is in data and X is in the value.
y=mydata[1,]
X=mydata[,4]
enter image description here
you should use rowMeans.
When you select a row you are selecting multiple variables and that results in giving you a dataframe.

I am trying to extract from a data set like this one above the numbers from the row named waiting into a new column but if I try to do the result is correct in some rows but others are giving me the last numbers on other rows .
I would like to have the information from the specific row including decimals, into a new column but not to get the other numbers .
Please try this
library(stringr)
data <- c('t1 waiting 1234', 'waiting 1234.5')
data <- trimws(str_extract_all(data, '\\s\\d.*'))

I need to align text in an ALERT STRING column with the row identified by number in an ID ROW column.
Additionally, I need to also align the same ALERT STRING text with the same ID ROW number AND with the ID matching that embedded in a string in the TEXT WITH ID column. (This double-check will sometimes be necessary with the real-world data.)
So far, I've only figured out how to align the ALERT STRING with the ID matching that embedded in the TEXT WITH ID column:
=LOOKUP(2,1/SEARCH(A2,$F$2:$F$11),$G$2:$G$11)
I appreciate any help folks can offer. You can find an editable copy of the workbook here:

UPDATE: Nayan provided a solution to the first part of this question (please see answer below). I'm still trying to work out a formula for the column D part of this question, in which the row reference shown in column E is combined with a match of the ID shown in column A with its corresponding value in one of the text strings in column F.
The best I've been able to come up with so far is a formula with a high failure rate:
=INDEX($G$2:$G$11,MATCH(ROW(D2),$E$2:$E$11,MATCH("*"&A2&"*",$F$2:$F$11,0)))
Any help with this part of the question will be greatly appreciated.
ROW([reference])
Returns the row number of a reference
E.g.: Row(B2) returns 2. If nothing provided like ROW() will also
return row number based on position of cell where it is called.
VLOOKUP(loolup_value, table_array, col_index_num, [range_lookup])
Looks for a value in the leftmost column of a table, and then returns a value in the same row from a column you specify (col_index_num)
By default - the table must be sorted in an ascending order.
Try this:
=VLOOKUP(ROW(B2),$E$2:$G$11,3,FALSE)
INDEX(array, row_num, [column_num]) INDEX(reference, row_num,
[column_num], [area_num])
Returns a value or reference of the cell at the intersection of a particular row and column, in a given range.
In this case, you have to get row_num with MATCH function.
MATCH(lookup_value, lookup_array, [match_type])
Returns a relative position of an item in an array that matches a specified value in a specified order.
match_type: 1 (Less than), 0 (Exact match), -1 (Greater than)
Try this:
=INDEX($G$2:$G$11,MATCH(ROW(B2),$E$2:$E$11,0))
Identity Data with Multiple Criteria Condition using MATCH()
=INDEX($G$2:$G$11,MATCH(1, (ROW(D2) = $E$2:$E$11) * (ISNUMBER(SEARCH(A2, $F$2:$F$11))),0))

This is the formula I was looking for in column D:
=INDEX($G$2:$G$11,MATCH(ROW(D2)&"*"&A2&"*",INDEX($E$2:$E$11&$F$2:$F$11,),0))
You can see it working here.
Nayan provided a great deal of help with answering this question, so I will mark his answer as the accepted solution.
Syeda Fahima Nazreen provided the example I referenced to figure out the formula shown above.

I have a data frame that looks kind of like this...but much larger
I want to look at the record_id column and shift the right side columns down when the row says admin_time. Then make that previous row NA. Then when I write it to a csv, I'll just use the na = "" to make those cells blank
For example, in the first few rows, it would look like this...
No need to try to recreate the data frame. I was thinking maybe a for loop would work with an embedded if statement to review the patient_id, record_id, and pk_day. I was just looking for alternate suggestions or how to use a statement within the loop to pick out the admin line and do what I mentioned above
Working with Google Sheets, scraping from an html table like this:
I want to get all the rows in JUST ONE CELL...
like this:
And I couldn't get the way to do it!
The expected result is to get all the table data in an unique cell...
replacing columns division, just by a blank space
and converting rows to simple text lines.
Any help, please? =(
NOTE: First values not always include de ":" character. Number of rows in table may vary.
Building from the previous answer you can try:
=QUERY(TRANSPOSE(ARRAYFORMULA(CONCAT(QUERY(TRANSPOSE(importxml_formula),,9^9),CHAR(10)))),,9^9)
Explaining the breakdown:
QUERY(TRANSPOSE(importxml_formula),,9^9)
This returns a table with one row with the number of columns as rows in the original table, with the result of each column is the data of each row in the table.
ARRAYFORMULA(CONCAT(QUERY(TRANSPOSE(importxml_formula),,9^9),CHAR(10))
Each column will be appended with CHAR(10), which corresponds to a line break.
TRANSPOSE(ARRAYFORMULA(CONCAT(QUERY(TRANSPOSE(importxml_formula),,9^9),CHAR(10))))
Transpose the table into 1 column, x number of rows, and finally the last QUERY merges the column into a single cell.
Sample Output:
Update:
Your IMPORTXML() already returned a single cell, and since they can be split by double space, you can use this formula instead:
=QUERY(ARRAYFORMULA(CONCAT(TRANSPOSE(SPLIT(IMPORTXML(A1,B1)," ",,FALSE)),CHAR(10))),,9^9)
try:
=INDEX(SUBSTITUTE(SUBSTITUTE(QUERY(SUBSTITUTE(FLATTEN(QUERY(TRANSPOSE(
your_formula_here
),,9^9)), " ", "×"),,9^9), " ", CHAR(10)&CHAR(10)), "×", " "))
I want to exclude entire rows that have blanks for a specific column....I dont want to show a row that has the first name column as a blank...I was thinking maybe a case statement would help with this
case when [First Name] = blank then exclude???
If this is SQL, in general you could do this:
SELECT *
FROM myTable
WHERE myCol IS NOT NULL
I had to add a calculated column that would be used as a flag, and then filter on the flag.
if(Len([First Name])>0,1,0)
Now I am able to filter on the calculated column to show only rows that have 1 in it (which will be the rows where First Name is not empty).
This doesn't delete the row from the dataset, but has the same effect in visualizations as if it had been.
