I am unable to rename the variables in datasummary. I don't think it has an option to do that. Any tips?
summary_vars <- as.formula(glue("any_prio + any_prio_on + any_prio_off + war_prio + war_prio_on +
war_prio_off + war_col + war_inc + war + GPCP + GPCP_g + GPCP_g_l + gdp_g +
gdp_g_l + y_0 + polity2l + polity2l_6 + deml + ethfrac + relfrac + Oil +
mtnest + lpopl1 + tot_100_g ~ mean*Arguments(na.rm = TRUE) + sd*Arguments(na.rm = TRUE) + N"))
TableA1 <- datasummary(data = mss_rep, summary_vars, booktabs = T,
fmt = 2,
col.names = c("", "Mean", "Standard Deviation", "Observations"),
caption = "DESCRIPTIVE STATISTICS") |>
kable_styling() |>
pack_rows("A. Civil Conflict Measures (1981–99)", 1, 9) |>
pack_rows("B. Rainfall Measures (1981–99)", 10, 12) |>
pack_rows("C. Economic Growth", 13, 14) |>
pack_rows("D. Country Characteristics", 15, 24)
TableA1
You could save the datasummary as a dataframe, do the renaming and apply a new kbl afterwards, e.g.
library(modelsummary)
library(kableExtra)
summary_df <- datasummary(mpg + cyl ~ mean, data = mtcars, output = "data.frame", fmt = 2)
# renaming
summary_df[,1] <- c("MPG", "CYL")
summary_df |>
kbl(booktabs = TRUE) |>
kable_styling() |>
pack_rows("A. Civil Conflict Measures (1981–99)", 1, 2)

checked the Lua print on the same line thread but io.write also is giving same error.
As in the comments wrote return() seems* the only way.
Example for redis-cli (set redis DB and use it in Lua)
(Collect Data and return as one string)
set LuaV 'local txt = "" for k, v in pairs(redis) do txt = txt .. tostring(k) .. " => " .. tostring(v) .. " | " end return(txt)'
Now the eval
eval "local f = redis.call('GET', KEYS[1]) return(loadstring(f))()" 1 LuaV
...shows whats in table: redis
(One long String no \n possible)
Exception: eval 'redis.log(2, _VERSION)' 0 gives out without ending the script but only on the server.
Than \n will work when you do...
set LuaV 'local txt = "" for k, v in pairs(redis) do txt = txt .. tostring(k) .. " => " .. tostring(v) .. "\n" end return(txt)'
...and the eval
eval 'local f = redis.call("GET", KEYS[1]) f = loadstring(f)() redis.log(2, f)' 1 LuaV
what will be regular express of this transition graph anyone?can make and explain this please i will be very thankful to him.
We can write some equations for this:
(q0) = e + (q1)a + (q3)b
(q1) = (q0)a + (q2)b
(q2) = (q1)b + (q3)a
(q3) = (q0)b + (q2)a
You can read these equations like this: "the set of strings that leads me to state X is the set of strings that lead me to state Y followed by symbol c, or the set of strings that lead me to state Z followed by symbol d, or..."
We can now solve these equations using substitution and a rule to eliminate self-references, namely:
if (q) = (q)x + y, then (q) = y(x*)
We can start solving the system by eliminating (q3):
(q0) = e + (q1)a + [(q0)b + (q2)a]b
(q1) = (q0)a + (q2)b
(q2) = (q1)b + [(q0)b + (q2)a]a
Distributing:
(q0) = e + (q1)a + (q0)bb + (q2)ab
(q1) = (q0)a + (q2)b
(q2) = (q1)b + (q0)ba + (q2)aa
We can get rid of (q1) now:
(q0) = e + [(q0)a + (q2)b]a + (q0)bb + (q2)ab
(q2) = [(q0)a + (q2)b]b + (q0)ba + (q2)aa
Distributing:
(q0) = e + (q0)aa + (q2)ba + (q0)bb + (q2)ab
(q2) = (q0)ab + (q2)bb + (q0)ba + (q2)aa
Grouping like terms:
(q0) = e + (q0)(aa + bb) + (q2)(ab + ba)
(q2) = (q0)(ab + ba) + (q2)(aa + bb)
Using the rule to remove self-reference:
(q0) = (aa + bb)* + (q2)(ab + ba)(aa + bb)*
(q2) = (q0)(ab + ba)(aa + bb)*
Substituting to get rid of (q2):
(q0) = (aa + bb)* + [(q0)(ab + ba)(aa + bb)*](ab + ba)(aa + bb)*
Distributing:
(q0) = (aa + bb)* + (q0)(ab + ba)(aa + bb)*(ab + ba)(aa + bb)*
Using the rule for self-reference:
(q0) = (aa + bb)*[(ab + ba)(aa + bb)*(ab + ba)(aa + bb)*]*
from the given transition diagram or DFA, equations for each state can be written as:
q0 = ε+q1.a+q3.b
q1 = q0.a+q2.b
q2 = q1.b+q3.a
q3 = q0.b+q2.a
substitute q3 in q2,
q2=q1.b+(q0.b+q2.a)a
q2=q2.aa+q0.ba+q1.b
substitute q1 in q2
q2=q2.aa+q0.ba+(q0.a+q2.b)b
q2=q2.aa+q0.ba+q0.ab+q2.bb
finally,
q2=q2(aa+bb)+q0(ba+ab)
It is in the form of t=tr+s
According to Arden's theorem,
the solution is t=sr*
So,q2=q0(ba+ab)(aa+bb)
Now substitute q3 in the equation q0,
q0=ε+q1.a+(q0.b+q2.a)b
q0=ε+q1.a+q0.bb+q2.ab
q0=q0.bb+(q1.a+q2.ab+ε)
substitute q1 in q0,
q0=q0.bb+(q0.a+q2.b)a+q2.ab+ε
q0=q0.bb+q0.aa+q2.ba+q2.ab+ε
q0=q0(bb+aa)+q2(ba+ab)+ε
Now substitute the q2 in the above equation,
q0=q0(bb+aa)+q0(ba+ab)(aa+bb)*(ba+ab)+ε
q0=q0((bb+aa)+(ba+ab)(aa+bb)*(ba+ab))+ε
Now q0 is in the form of t=tr+s so the solution is t=sr*
q0=((bb+aa)+(ba+ab)(aa+bb)(ab+ba))
The Regular Expression for the given DFA is:
q0=((bb+aa)+(ba+ab)(aa+bb)*(ab+ba))

n = 1 : 1
n = 2 : 1
n = 3 : Fib(n-1) + Fib(n-2) + Fib(n-3) = Fib(2) + Fib(1) + Fib(0) = 1 + 1 + 0 = 2
n = 4 : Fib(n-1) + Fib(n-2) + Fib(n-3) = Fib(3) + Fib(2) + Fib(1) = 2 + 1 + 1 = 4
Basically, you add the 3 previous number before n.
I want to create videos for multiple cameras stored in MySQL database. At intervals of every 1 hour the duration of video should be 59 mins and 59 secs. The videos should be then uploaded to azure blob storage.
However, every time a video is created, it is of a smaller duration (for example, 44 or 45 mins). I am not getting any errors. What am I doing wrong? any suggestion will be of great help. Thank You.
